Hello, I have a problem with agent++ under NT. as soon as I turn on event logging with DefaultLog::log->set_filter(EVENT_LOG,3); The program dies at the first point to do logging. The same works perfectly under Linux. I've used agent++ 3.4.4a and 3.5.1a and snmp++ 3.0j and 3.1.5. Does anyone knows how to get logging under NT ? Thanks Thomas
