There are two issues that might be affecting you here:

1. We may have a leak of file descriptors on the logic that opens the 
keystore. Can you take a look at the following change? Can you apply it 
and let us know if it fixes your problem?

http://gerrit.ovirt.org/#/c/5423

2. You may be having a problem with the file descriptors limit due to 
other issues. During setup we should increase the file descriptor limit 
from 1024 (the default) to 65535, but we do that for the "jboss" user 
instead of for "ovirt". The fix for this issue is in review:

http://gerrit.ovirt.org/#/c/5375

The workaround for this is to edit the /etc/security/limits.conf file 
and replace "jboss" with "ovirt", then restart the engine.
