Hello,

We receive 1 cluster reboot random (HP Blade server) and our WHMCS connect to this cluster is really slow. We check pveproxy status and it showing this output:

As the error message saying, you have too many files open.
This can happen if you use Containers in this case you should increase the open files limit in the limits.conf .

This is strange. We did not use any LXC on this cluster. We have 2 incidents last weekend. Proxmox random reboot on Saturday and Sunday after upgrade to Proxmox latest version. Is this the root cause of issue?

If you have no LXC than I would investigate what process has so many files open.

You can use this
Code:
#!/bin/bash

cd /proc
for pid in [0-9]*
do
   echo "PID: $pid \tFD: $(ls /proc/$pid/fd/ | wc -l)"
done
