Repeating syslog error?

[TGW]

I have Proxmox running a server with 32GB RAM (of which about 40% is used), yet I am getting this entry in the node syslog about 45-60 mins, regularly:

Aug 06 15:31:27 xxxxxxxx pve-firewall[1527]: restarting server after 365 cycles to reduce memory usage (free 91996160 (5246976) bytes)

I do not understand why this is occurring, someone have a little light
to shed on this problem . . .

Thanks in advance!

the pve-firewall daemon tries to minimize memory consumption by restarting itself if it uses too much memory

Thanks for the reply,

Is this a 'normal' operation in Proxmox, or is there something I would need to adjust?
When you say pve-firewall daemon is restarting itself, this does not include the server
node as whole, but just the firewall, correct?

Thanks

some of our daemons do this, and no this is not adjustable, but should be harmless

yes
