------------------------------------------
Any updates on this, Rakesh? Are you still seeing this problem, do you already
know the reason, have any further debug data and your configuration available?
> Log4cxx SocketAppender leads to application crash
> -------------------------------------------------
>
> Key: LOGCXX-441
> URL: https://issues.apache.org/jira/browse/LOGCXX-441
> Project: Log4cxx
> Issue Type: Bug
> Components: Appender
> Affects Versions: 0.10.0
> Environment: CentOS, RHEL, C++11
> Reporter: Rakesh Sehgal
> Labels: features
>
> I am using log4cxx and recently started working with SocketAppender. I use
> the following:
> java org.apache.log4j.net.SimpleSocketServer 4712 log4j-server.properties
> and am able to write logs on the server. I do also have a local SizeRollover
> policy setup. This all works fine, until I stop running the
> SimpleSockerServer. At which point my C++ application crashes, I think after
> the ReconnectionDelayTime specified in the properties file.
> Below is the gdb output from crash:
> 0 0x0000003c5fa0e6fd in write () from /lib64/libpthread.so.0

> As an improvement, Is it possible to make log4cxx write logs to a local file
> in case the server stops? If I start the server again, before the application
> crashes, SocketAppender does not receive the logs again. Any other
> suggestions to send logs over the network?
