Re: LOG4CXX crashes
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.

Guten Tag Rai, Ashish,
am Dienstag, 4. April 2017 um 03:45 schrieben Sie:
> Log4cxx version : Version: 0.10.0 (installed in 32-bit because our application is in 32-bit)
Is this a pre-build version shipped by your distribution? If so,
please try again with your own build of a current trunk, which has a
lot of bug fixes applied since 0.10.0 has been released.
Additionally, this way you are able to use the test suite which might
reveal something regarding your issue. If your distribution provides
the test suite for your current version already as well, I suggest
start using that first.
You can find build instructions for both versions online:
https://logging.apache.org/log4cxx/latest_stable/index.html
https://logging.apache.org/log4cxx/next_stable/index.html
Mit freundlichen Grüßen,
Thorsten Schöning

RE: LOG4CXX crashes
Posted by "Rai, Ashish" <as...@delta.com>.
Log4cxx version : Version: 0.10.0 (installed in 32-bit because our application is in 32-bit)
Our application is not a multithreaded application.
This crash has happened few time. Most of the time this functions work fine.
Thanks & Regards,
Ashish Rai
