503 Error at access on an smb-storage over webdav, after nextcloud runs a time

Nextcloud version (eg, 10.0.2):
Operating system and version (eg, Ubuntu 16.04): Debian 8.7
Apache or nginx version (eg, Apache 2.4.25): 2.4.10
PHP version (eg, 5.6): 5.6
Is this the first time you’ve seen this error and can you replicate it?:
no thats not the first time, yes I can reproduce it
The issue you are facing:
I have a smb storage connectet and connect with normal windows over webdav, after some time (15-30 Minute) I get an 503 (STorage is temporarily not available)
After a restart of apache and smb, it works fine, after 15-30 minute I can´t access the storage with webdav
In the webfrontend, I can access the storage!
