Every time after restart of PBS server, backups just stop working a we need to reboot all PVE nodes.

Bash:

Backup job is just stuck.

After some time backup job failed with error:

Bash:
ERROR: backup write data failed: command error: write_data upload error: pipelined request failed: timed out

Restore from same backup server works just fine but vzdump nope. Currently only fix for this is reboot every node. Any idea where can be a problem ?

For backup we are using Dell R530 (PERC H730 raid6 6x10TB single ext4 partition)
 
Any idea how to restart pbs connector on PVE ? I tried reload network interfaces and remove an add PBS storage in PVE but nothing helps. Only reboot
 
you could post the syslog/journal from the time it's not working, maybe there is a hint there what's going wrong
