[tao-users] [tao_cosnotification] coredump

[Tomek]

TAO version 2.3.1
ACE version 6.3.1


Red Hat Enterprise Linux 7.6.1-80.el7

I am running the tao_cosnotification with the following options:
/SA/tao/bin/tao_cosnotification -NoNameSvc -IORoutput
/SA/data/fp1/ca/tmp/ntfy.ior -ORBDottedDecimalAddresses 1
-ORBListenEndpoints iiop://:20001


It sometimes drops a core. It happens occasionally from time to time and I
can not determine any relation to suppliers' or consumers' behavior.

The core stack is listed below. Is this a bug or can I do anything to avoid
those coredumps?
