I have managed to trace this to a possible bug in the db3 library, installed from the RH rpm on 7.1. db3-3.1.17-7. The libraries are correctly linked, but lmtpd dies with a signal 11 at line 313 of lib/cyrusdb_db3.c ( r = db->get(db, tid....)). Does anyone have any idea of this problem? Bugfixes available? Or do I have to use the force? Devdas Bhagat -- Better living a beggar than buried an emperor.
