Hi all,
I've got a series of programs that monitor various things on a CentOS Stream 8 VM host. All of these scripts work when called directly. However, when I have a parent program that calls all the little programs in series, I found that some virsh calls hang.
Initially, there were two scripts that were hanging repeatedly. Once called 'virsh net-list --all --name', so I changed it to check for configs in '/etc/libvirt/qemu/networks/', and that script started working. The other script though calls 'virsh list --all', and that can't be easily swapped out, so I really need to find the source of these hangs.
Whenever the hang happens, about 30~45 seconds later, I see
'libvirtd[1643714]: Cannot recv data: Connection reset by peer'.
I think the issue is striking other scripts that run, but this
scenario is happening predictably and consistently right now.
I thought it might be a concurrent connect limit or a problem with how many times virsh is called by a script, so I wrote a test script that kept calling 'virsh list --all' each second, but it was close to 100 calls without hanging, far more that all the calls in my scripts combined, so I don't think that's it.
Any advice/guidance would be very much appreciated!
