[Users] Weird crash of oVirt-3.3.2-el6

[Joop]

Hi All,

Just saw that something has gone 'wrong' in my oVirt installation and I 
can't make sense of it.
Full logs are placed in a save place but I would like to start with the 
following from /var/log/message on ovirt04:
Jan 30 07:31:52 ovirt04 vdsm TaskManager.Task ERROR 
Task=`2a424ca3-19f6-4e01-9e42-ec377655c6f1`::Unexpected 
error#012Traceback (most recent call last):#012  File

**kwargs)#012  File "/usr/share/vdsm/storage/hsm.py", line 3049, in get

volUUID, bs=1))#012  File "/usr/share/vdsm/storage/fileVolume.py", line

callCrabRPCFunction#012    raise Exception("No free file handlers in

  pool

 From that point on  it goes downhill. Ovirt04 was the SPM, that got 
transferred to ovirt02, all VM's on ovirt04 are set to paused, but only 
in the logs and the webui. In real life they are running fine (virsh -r 
list on ovirt04 confirms that).
I can select all paused VM's and 'run' them and that clears up de webui 
and doesn't harm the VM's sofar as I can tell but shouldn't be necessary.
