Segmentation fault in _event_sleep

I'm currently using Orbix version v3.3.10. The Orbix server at some times stops listening to the Corba client request with core dump showing a segmentation fault in _event_sleep method? Is there are any issues in the above said Orbix version? is it fixed in any of the later versions?
