To rule it out completely, watch it during your test:

   watch -n 0 'cat /proc/sys/kernel/random/entropy_avail'

It might start blocking when it gets as low as 100 (healthy seems to be 
above 1000). If you're at the console (not a remote terminal), type on 
the keyboard to add entropy and see if this helps. If it does, you may 
have a cyrus-sasl that uses /dev/random (the default). Check the source 
RPM to verify, and adjust it to use /dev/urandom to stop the blocking.
