Hi, We are getting crashes from log4cxx implementation in our application. Our application is running on Linux 2.6.32-358.el6.x86_64. It C++ based application using orbix to interact with Java based GUI.
Please find below stack trace for core dump : #0 0x0077a430 in __kernel_vsyscall () #1 0x013b9b11 in raise () from /lib/libc.so.6 #2 0x013bb3ea in abort () from /lib/libc.so.6 #3 0x013f99d5 in __libc_message () from /lib/libc.so.6 #4 0x013ffe31 in malloc_printerr () from /lib/libc.so.6 #5 0x014033ff in _int_malloc () from /lib/libc.so.6 #6 0x0140400e in malloc () from /lib/libc.so.6 #7 0x03c9a09a in operator new(unsigned int) () from /usr/lib/libstdc++.so.6 #8 0x03c76ed6 in std::basic_string<char, std::char_traits<char>, std::allocator<char> >::_Rep::_S_create(unsigned int, unsigned int, std::allocator<char> const&) () from /usr/lib/libstdc++.so.6 #9 0x03c78029 in std::basic_string<char, std::char_traits<char>, std::allocator<char> >::_Rep::_M_clone(std::allocator<char> const&, unsigned int) () from /usr/lib/libstdc++.so.6 #10 0x03c78578 in std::basic_string<char, std::char_traits<char>, std::allocator<char> >::reserve(unsigned int) () from /usr/lib/libstdc++.so.6 #11 0x03c78a5b in std::basic_string<char, std::char_traits<char>, std::allocator<char> >::append(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) () from /usr/lib/libstdc++.so.6 #12 0x07653c0f in log4cxx::pattern::LiteralPatternConverter::format(log4cxx::helpers::ObjectPtrT<log4cxx::spi::LoggingEvent> const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> >&, log4cxx::helpers::Pool&) const () from /log4cxx/lib/liblog4cxx.so.10 #13 0x076778e5 in log4cxx::PatternLayout::format(std::basic_string<char, std::char_traits<char>, std::allocator<char> >&, log4cxx::helpers::ObjectPtrT<log4cxx::spi::LoggingEvent> const&, log4cxx::helpers::Pool&) const () from /log4cxx/lib/liblog4cxx.so.10 #14 0x076b6636 in log4cxx::WriterAppender::subAppend(log4cxx::helpers::ObjectPtrT<log4cxx::spi::LoggingEvent> const&, log4cxx::helpers::Pool&) () from /log4cxx/lib/liblog4cxx.so.10 #15 0x0768aca4 in log4cxx::rolling::RollingFileAppenderSkeleton::subAppend(log4cxx::helpers::ObjectPtrT<log4cxx::spi::LoggingEvent> const&, log4cxx::helpers::Pool&) () from /log4cxx/lib/liblog4cxx.so.10 #16 0x076b5da7 in log4cxx::WriterAppender::append(log4cxx::helpers::ObjectPtrT<log4cxx::spi::LoggingEvent> const&, log4cxx::helpers::Pool&) () from /log4cxx/lib/liblog4cxx.so.10 #17 0x07604aa0 in log4cxx::AppenderSkeleton::doAppend(log4cxx::helpers::ObjectPtrT<log4cxx::spi::LoggingEvent> const&, log4cxx::helpers::Pool&) () from /log4cxx/lib/liblog4cxx.so.10 #18 0x07601065 in log4cxx::helpers::AppenderAttachableImpl::appendLoopOnAppenders(log4cxx::helpers::ObjectPtrT<log4cxx::spi::LoggingEvent> const&, log4cxx::helpers::Pool&) () from /log4cxx/lib/liblog4cxx.so.10 #19 0x0765973d in log4cxx::Logger::callAppenders(log4cxx::helpers::ObjectPtrT<log4cxx::spi::LoggingEvent> const&, log4cxx::helpers::Pool&) const () from /log4cxx/lib/liblog4cxx.so.10 #20 0x076599dd in log4cxx::Logger::forcedLog(log4cxx::helpers::ObjectPtrT<log4cxx::Level> const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, log4cxx::spi::LocationInfo const&) const () from /log4cxx/lib/liblog4cxx.so.10 #21 0x080b07cd in AppServer::getSomething (this=0x8a54cb8, env=...) at AppServer.cpp:406 #22 0x080bae04 in AppModule_AppServerIntfcAppServer::getSomething (this=0x8a561d8, IT_env=...) at AppServer.h:243 #23 0x0829bedb in AppModule::AppServerIntfc_dispatch::dispatch (this=0x8a41298, IT_r=..., IT_isTarget=1 '\001', IT_pp=0x8a561d8) at AppModuleS.cc:229 #24 0x019fbdfe in ContextClassS::continueDispatch(RequestS&, CORBA::Filter*, CORBA::PPTR*) () from /orbix/lib/liborbixmt.3.3.gcc411.so.1 #25 0x019fc109 in ContextClassS::continueThreadDispatch(RequestS&) () from /orbix/lib/liborbixmt.3.3.gcc411.so.1 #26 0x01a06681 in IT_BOAImpl::continueThreadDispatch(CORBA::Request&) () from /orbix/lib/liborbixmt.3.3.gcc411.so.1 #27 0x01a06139 in CORBA::BOA::continueThreadDispatch(CORBA::Request&) () from /orbix/lib/liborbixmt.3.3.gcc411.so.1 #28 0x0064b911 in ThreadFilter::threadPool() () from /apps/app/lib/libapp.so #29 0x0064b8bb in ThreadFilter::runThreadPool(void*) () from apps/app/lib/libapp.so #30 0x00967a49 in start_thread () from /lib/libpthread.so.0 #31 0x01471aee in clone () from /lib/libc.so.6 This is code snippet for function : CORBA::Long AppServer::getSomething (CORBA::Environment& env) throw (CORBA::SystemException) { LOG4CXX_DEBUG (logger,"AppServer::getSomething called!" ); something++; return something; } Let me know if you need more detail.
