Hi
I have the same problem and I could not solve. I have installed the version
apache-log4cxx-0.10.0. apr-1.3.6 and apr-util-1.3.8. in a Red Hat 5 x64
I tried with the patch 596934 and does not work.
When the program ends gives an exception
terminate called after throwing an instance of
'log4cxx::helpers::MutexException'
what(): Mutex exception: stat = 22
./tester.sh: line 71: 17226 Aborted ./tester
