To reproduce we added:
TAO/orbsvcs/tests/Security/MT_SSLIOP/run_test_heavy.pl

When running SSLIOP under heavy load we get errors like the ones below, we have
seem someone make a comment that multiple threads shouldn't use the same SSL
connection else things like this can happen. We have not been able to find the
problem in the TAO SSLIOP implementation at this point. We have tried to
reproduce this problem also with ACE SSL but that works perfect under extreme loads
