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 issuestest in the above said Orbix version? is it fixed in any of the later versions?

  • What platform are you running on and what is the C++ runtime? I suspect this is due to Orbix 3.3.10 running on an unsupported platform or compiler as I would not expect any problems in a pthread_cond_wait(). This is very basic low level idle waits.

    Note that the latest version of Orbix 3.3 is 3.3.13. If you are supported I would strongly recommend upgrading to that version. It is fully binary compatible and all you need to do is drop in the libraries. No recompilation is necessary.
