I attached a pmap of java process after start and will provide a new one in a few hours.
May be a dupe of https://bugzilla.redhat.com/show_bug.cgi?id=1028966. I will implement the suggested workaround of comment 27 and have a look.
do you have the conflicting openjdk version? upgrade or downgrade it should work as well.
Disabling Security Provider does indeed solve the problem. Engine runs 2 days without problems. Bug can be closed.
closing as issue is in openjdk, not ovirt. new openjdk release fixes it. workarounds available: downgrade or upgrade openjdk as well as disabling the problematic security provider.
