Hi,
    I am using qpid-cpp-server-0.18-20.el6.x86_64 on RHEL 6.5 x64. All was 
working perfectly fine and suddenly qpidd started misbehaving. The bottom line 
is that when I am trying to start it now I am getting below error:

When I start qpidd from command line as a user, it runs fine but not as a qpidd 
user. Also after I removed all the content from /var/lib/qpidd, I could start 
qpidd again. 
So obviously it's some kind of memory limit issue but I am trying to understand 
what is the limit exactly? And why this happened now? what triggers this?

I am using qpid for OpenStack Havana.
