Welcome to SUSE Linux Enterprise Server 11 (x86_64) - Kernel \r (\l). Openhpi version : Openhpi-3.5.x

Back Trace Analysis: Discovery thread holds the mutex lock and wait for the event thread to join, But oa_soap_event thread is blocked indefinitely in SSL_connect() call.

But this issue occurs very rarely.

Attached the full back trace of all the thread which are still alive even after kill -15.

The attached patch avoids the thread hangs at the plugin level. The infrastructure calls the discovery even after the SIGTERM / SIGINT is issued. Even after this change, there is a small chance that plguin could be in discovery when the variable it set. Infrastructure also needs to change a bit. It needs to stop making a new plugin discovery call as soon as the SIGTERM / SIGINT is issued.
