qpidd occasionally goes into rage mode and opens up a lot of file socket to 
/var/lib/qpidd/rhm/jrnl/000X/*.jdat

At this point, any command issue to pulp cli will cause a

It has been observed on functioning system that if pulp is continued to be used, the number of open sockets will continue to grow without ever decreasing.  

For example, pulp-qe is working

[root@pulp-qe qpidd]# lsof | grep "qpidd"|wc -l
630

after one successful run of automated test,

[root@pulp-qe qpidd]# lsof | grep "qpidd"|wc -l
639

Given this, it's only a matter of time before this error will be encountered on this system as well.
