Subject Re: LOG4CXX crashes
Date Tue, 04 Apr 2017 00:02:45 GMT
Ashish,

A few questions for you:


   1. What version of log4cxx are you running?
   2. Are you running log4cxx in a multi-threaded application?  If yes, the
   current versions of log4cxx do have problems with multithreaded
   applications, and that could cause a problem.
   3. Does this happen all the time?  If it's not happening all of the time
   it sounds like it could be memory corruption of some kind.
