Public bug reported:

Hi,

We have upgraded to Wallaby and in our computes we are observing nova-compute service is down.
The logs seem to indicate "Too many open files". Can someone help us with this issue.

-----------
:~# lsof -P -M -l -n -d '^cwd,^err,^ltx,^mem,^mmap,^pd,^rtd,^txt' -p 2394860  -a | awk '{if (NR>1) print}' | wc -l
1031
--------

The above process is a nova-compute process

The OS version is Ubuntu 20.04. The hypervisor is KVM

I am attaching the lsof output for this process. Please check that.


Thanks
