[Log4cplus-devel] [log4cplus:bugs] #335 AsyncAppender leads to memory leaks

[Guglielmo F. <gf...@us...>]

I am observing memory leaks in log4cplus compiled as static library with windows visual studio 2015, since I cannot terminate the thread which needs to run continuosly in a server, should I call log4cplus::threadCleanup() periodically or what ?
