Hello - first, thanks for all your efforts with Nextcloud and the app. I’m impressed with how seamless everything generally is.
I wonder if anyone can help with an issue - essentially any access from Nextcloud iOS app (188.8.131.52 from either iPhone 5S or SE, or iPad Air2) causes my self-hosted server (18.0.6 running on RPI 4) to crash.
Nextcloud works well through web interface and OSX sync app. I have also tried the android app which does not cause the issue.
The crash: load average goes north of 6 (sometimes into double digits), seems to be processor in %wa causing this increase. App shows timeout errors / doesn’t display contents of folders. Server log shows PHP memory exceeding limits (initially 512MB but exceeded 1GB also when I increased it). I switched off previews on the server to no avail.
It seems like the iOS app is doing something which is really taxing the server. Any ideas what I should do next in terms of troubleshooting?
