our server hung for 2 hours today.
the log shows
2010-06-11 20:27:56,852 INFO - Saving data, INCREMENTAL, clock:15094434027
2010-06-11 20:27:56,852 INFO - ========================================

2010-06-11 23:07:50,223 INFO - Save Type: INCREMENTAL
the code is
LOG4CXX_INFO(logger_, "Saving data,
"<<(saveType==DATA_SAVE_TYPE_COMPLETE?"COMPLETE":"INCREMENTAL")<<",
clock:"<<clock->now());
balabal
LOG4CXX_INFO(logger_, "========================================");

("<<totSize/(float)(1024*1024)<<" M)");
LOG4CXX_INFO(logger_, "Save Type:
"<<(saveType==DATA_SAVE_TYPE_INCREMENTAL?"INCREMENTAL":"COMPLETE"));
the logger_ is initialized in the constructor as
log4cxx::PropertyConfigurator::configureAndWatch("logger-w.cfg");
logger_ = log4cxx::Logger::getLogger("World");
and the config file is
log4j.rootLogger=INFO, stdout, R

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

there is no log rolling between log "====" and "Save Memory". the log shows it
hung 2 hours between these two lines. Could anyone tell me why this happened?
thanks
