[reSIProcate] Is this the cause of random solaris cores from resip related to memory?
Hello,
I am using a resip version from April and seeing random cores on solaris
under load. This is what I have found so far. Experts, please chime in..
Running a MT application based on resiprocate on solaris multi-processor
box results in random core dumps. On running purify, I see lot of MRE
(malloc re-entered). Doing some investigation, found a Sun article that
says that the following calls are not MT safe and should not be used. I
did a quick grep and found resip does use localtime and gmtime (without
the _r at the end). I have not checked the others..
This is the link if anyone is interested..

Does it make sense that my cores may be caused by the above? I have been
seeing random core dumps related to malloc and free on solaris, and most
of them have been related to:
