Hi,
I've initiated 11 stunnel processes in the same server. Each of the
stunnel process has its own client certificate to communicate to
application server. However after sometime of execution, the stunnel
processes are crached (dying off) one by one. below is the last portion of
my log (with debug level 7). I don't see any critical error in the log.
Would appreciate if someone could highlight to me what cause the problem or
anyone has similar experience.
