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.
