Re: [ovirt-users] question mark in oVirt - "cannot acquire state change lock"
Hello, some requested outputs Vdsm generate a huge count of records in time, so I'm not shure if "hang" time is still included . Problems occured 17-feb-2016 17:00-18:00 when VM shutdown was requested. But some performance problems occured a day before ( I'm not shure about application problem = JAVA = running EBS ) In mail before I attached pointers to bugs with any workaround killall -9 libvirtd rm /var/run/libvirtd.pid /etc/init.d/libvirt-bin restart which would solve current situation. Is this workaround safe enought?? Will stay VMs running ??? THX for any help, because I can't reboot hypervizor due huge DB traffic and no VM migration possibility via oVirt engine. ( mem synchro overloaded ?? ) Pa. PS: logs sent directly to RH.
