Hi guys,
these logs appear on both hosts just like the result of --vm-status. tried to tcpdump on ovirt hosts and gluster nodes but only packets exchange with my monitoring VM(zabbix) appeared.

I'd welcome any details on this "stalled file descriptor" problem. Is
there a bug filed with some details like logs, sysrq-t and maybe even
tcpdumps? If there is an easy way to reproduce this behaviour, I can
surely look into it and hopefully come up with some advise or fix.
Thanks,
Niels
