Hi Gurus,

I am not subscribed to this list so please reply to my personal email

Our multi-threaded application is crashing and the pstack of the core
points to openssl. We r using openssl version 0.9.6g
and http://www.openssl.org/news/changelog.html points to a bug getting
fixed on flush but don't know whether our problem is related
to that or not. We can see that the code path for
SSL_CTX_flush_sessions is invoked when the auto flush at 255
connections is called.
But, why should our application crash?
The pstack output is given below for you reference. Please observe
this portion from the detailed pstack output given below:

001f29a4 SSL_CTX_flush_sessions (3464fc, 100, 93e230, 362020,
