[pve-devel] pveproxy issue

[Guy Loesch]

Hi Dietmar,

I am using Proxmox (great product) in a lab context for my students.  
Maybe you remember our mail exchange last year where we had an issue  
with identical mac address generation when all of my students created  
a new machine at the same time. You bug-fixed the issue very quickly.  
Thanks again.

This year I have a new issue. Before starting this year's course I  
updated Proxmox to the latest version.

When the students (11 in all) are working all together on the Proxmox  
GUI, pveproxy hangs after a quite a short time and they get  
"Communication failure(0)", "Loading..." "Server Offline?" or "Time  
out" messages. I have to restart the pveproxy service to get back to a  
working GUI. All the machines are working fine when accessing them via  
noVnc or remote desktop so the problem is only related to pveproxy.

Observations:

I did not have that problem last year. Is there any parameters related  
to pveproxy that got changed due to the upgrade?

I discovered the keep-alive value in /usr/bin/pveproxy, and I tried  
values from 10 to 900 (default is 100), with no positive effect.

I installed nginx in a container. Accessing the Proxmox GUI via nginx  
improved the situation a lot. I still get same "hangs" but they appear  
a lot later, less often and recover after a while. I do not have to  
restart pveproxy.
Unfortunately I have no solution yet to acces the novnc this way.


Is there anything else I can try?
