Symptoms
After upgrade to BA 6.0.x the log BM.log is not written anymore. We need logging to be working correctly.
Answer
The descried behaviour is correct for BA 6.0. In BA 6.0 there are no separate processes for BM and other BA containers (refer to kb #124648). The system logs in BA are:
/usr/local/bm/log/generic_worker.log
/usr/local/bm/log/scheduler.log
/usr/local/bm/log/WWW.log
and *.out.logs
