Lots of SABRE errors, NC to slow to use

Mecallie · December 1, 2021, 8:42am

[/details]

Nextcloud version (eg, 20.0.5): 23.0.0 RC3 and 22.2.2
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20 LTS
Apache or nginx version (eg, Apache 2.4.25): nginx latest
PHP version (eg, 7.4): 7.4

The issue you are facing:

My NC instance has been incredibly slow for about a week now. First I thought it had something to do with the host. Load average was above 3 sometimes. I did some troubleshooting and disabled THP. Dunno if that was the only thing, but the load average is now at ~0.1 again. Performance is still so slow that my NC is not usable anymore.

I even upgraded to 23, to see if that fixed anything: same as on 22.

As far as I know I did not change anything on my server to cause this. (3 core, 4GB, 2 users)

Is this the first time you’ve seen this error? (Y/N): yes

Steps to replicate it: dunno

I used to use an external ical (or caldav) calendar for holidays and such. That no longer exists, I am not sure if I removed that link at some point. It does not show in my calender (when I am able to open it) app in any case.

I am going to take a look at that api.yagoal.co: I think that might be a hacking attempt?

Any thoughts as where I would have to start troubleshooting this?

gas85 · December 1, 2021, 12:58pm

Did you check what program/service is causing it, e.g. with htop or top?
I would also monitor Network activity if you are simply bombed with dummy requests.

Mecallie · December 1, 2021, 1:36pm

As far as I could tell php-fpm was using most cpu. But that was still not nearly 100%. I am beginning to wonder if slow external storage could be the problem?

Also I am wondering if there is a way to check which contact (vcard) is corrupt? The contacts page does not seem to want to load at all most of the time now. And when it does I get “contact not found” whenever I click a contact. Syncing still seems to work though…

Since this week I see CPU loads of 100% sometimes on my NAS. Seems to be whenever Nextcloud is accessing files. Never had a load of more than 25% before last week.

I have all my files stored there and make them available via external storages via Nextcloud.

gas85 · December 1, 2021, 1:48pm

As I know, Contacts are saved in DB e.g. in oc_addressbooks, not on a storage at all.

Mecallie · December 1, 2021, 2:00pm

I think so too. So I am thinking of two separate issues.

One: slow storage (is this the cause, or a result?)
Two: some kind of corruption in my address book or a single vcard…

gas85 · December 1, 2021, 2:20pm

Sure, if storage slow it could cause a lot of issues.

I believe you are using Contact App? Check with a Developer Tools - Network of your browser if requests are passing trough quick enough.
To check is REPORT to /remote.php/dav/addressbooks/users/USER/contacts/. Its delivers overview of all contacts and should be fast.

Then you can click on any contact it will retrieve data of it as PROPFIND to /remote.php/dav/addressbooks/users/USER/contacts/<uuid>.vcf (please ignore 404 on ...photo not all contact having them):

IDK how many contacts do you have, but if you click all of them you can may be find one that fails.

Mecallie · December 2, 2021, 1:04pm

Alright, found out what was causing the terrible (non-existent) performance: Camera RAW Previews .

What happened: we where cleaning up pictures, moving them from “live” storage to SMB mounted External storage. When NC detected the new files on external storage the Camera RAW Previews app was generating previews for all the files (not just raw?) and overloading the NAS.

After removing Camera RAW Previews app my NAS load dropped back to 1%.

Still getting errors from the contacts app. I am also noticing that the avatars/pictures are not showing and are being generated every time I open the contacts app. Will look in to that when I have the time.

gas85 · December 2, 2021, 1:28pm

Oh, thats cool! I have had similar issue with Recognize App, but it utilized Network a lot and didn’t hit my CPU limits:

Mass periodical external Storage ALL files download

opened 12:50PM - 17 Nov 21 UTC

GAS85

**Describe the bug** As per https://github.com/nextcloud/server/issues/29744 … Since last update a lot of data downloaded (around 5 MB/s for 10 Min = around 3 GB downloaded) from external storages. With `tcptrack` find out that all traffic goes to only 1 external share - [Magenta Cloud](https://www.magentacloud.de/). Files were not changed since 2017 and correctly tagged, but still downloaded to be analyzed each 10-20 min. **To Reproduce** Steps to reproduce the behavior: 1. Use external Storage via WebDav 2. Upgrade to the latest Recognize App 3. From some point periodical mass download will appear: ![grafik](https://user-images.githubusercontent.com/6813635/142160003-e647c847-cfb8-417a-abb3-53e867ad55ac.png) 4. Check `tmp` Folder and it is full of files from the external storage (was checked by download and open few of tmp files): ```bash ls -la /tmp/oc_* -rw------- 1 www-data www-data 0 Nov 17 09:19 /tmp/oc_tmp_0ABNip -rw------- 1 www-data www-data 6519718 Nov 17 09:19 /tmp/oc_tmp_0ABNip-.JPG -rw------- 1 www-data www-data 0 Nov 17 09:17 /tmp/oc_tmp_0BASfm -rw------- 1 www-data www-data 4757 Nov 17 09:17 /tmp/oc_tmp_0BASfm-.png -rw------- 1 www-data www-data 0 Nov 17 09:16 /tmp/oc_tmp_0JPaKn -rw------- 1 www-data www-data 14135 Nov 17 09:16 /tmp/oc_tmp_0JPaKn-.png -rw------- 1 www-data www-data 0 Nov 17 09:16 /tmp/oc_tmp_0Ytsul -rw------- 1 www-data www-data 400761 Nov 17 09:16 /tmp/oc_tmp_0Ytsul-.png -rw------- 1 www-data www-data 0 Nov 17 09:16 /tmp/oc_tmp_0iJTEp -rw------- 1 www-data www-data 8528 Nov 17 09:16 /tmp/oc_tmp_0iJTEp-.png -rw------- 1 www-data www-data 0 Nov 17 09:17 /tmp/oc_tmp_0xJSqp -rw------- 1 www-data www-data 3928 Nov 17 09:17 /tmp/oc_tmp_0xJSqp-.png -rw------- 1 www-data www-data 0 Nov 17 09:16 /tmp/oc_tmp_11tZKo -rw------- 1 www-data www-data 37630 Nov 17 09:16 /tmp/oc_tmp_11tZKo-.png -rw------- 1 www-data www-data 0 Nov 17 09:16 /tmp/oc_tmp_1ML1Nl -rw------- 1 www-data www-data 33559 Nov 17 09:16 /tmp/oc_tmp_1ML1Nl-.png -rw------- 1 www-data www-data 139075 Nov 17 09:16 /tmp/oc_tmp_1UwNMo -rw------- 1 www-data www-data 0 Nov 17 09:16 /tmp/oc_tmp_1VtGYl -rw------- 1 www-data www-data 7168 Nov 17 09:16 /tmp/oc_tmp_1VtGYl-.xls -rw------- 1 www-data www-data 0 Nov 17 09:17 /tmp/oc_tmp_1YnGln -rw------- 1 www-data www-data 6147 Nov 17 09:17 /tmp/oc_tmp_1YnGln-.png -rw------- 1 www-data www-data 0 Nov 17 09:16 /tmp/oc_tmp_1dvkdo -rw------- 1 www-data www-data 3394241 Nov 17 09:16 /tmp/oc_tmp_1dvkdo-.pdf -rw------- 1 www-data www-data 0 Nov 17 09:18 /tmp/oc_tmp_2DeKSp -rw------- 1 www-data www-data 48512299 Nov 17 09:18 /tmp/oc_tmp_2DeKSp-.mp4 .... ``` 5. Seems a lot of data downloaded (around 5 MB/s for 10 Min = around 3 GB downloaded). External Storage is around 3 GB big. 6. Check files in external Storage - all are tagged with `Tagged by recognize` and unmodified since years: ![grafik](https://user-images.githubusercontent.com/6813635/142202162-01f74dbf-071d-41ea-93bd-f47da018370f.png) 7. Amount of recognized files will remain the same. And Cron Job will use whole time of it --> https://github.com/nextcloud/server/issues/29744#issuecomment-971435490 **Expected behavior** Unchanged files should not be downloaded again and again for analyses. **Recognize (please complete the following information):** - JS-only mode: No - Enabled modes: object detection **Server (please complete the following information):** - Nextcloud: 21.0.7 - OS: Ubuntu 20.04 - RAM: 16GB - Processor Architecture Zen 3 (AMD Ryzen 3 3200G)
