Using Cyrus 1.6.24 and deliver -e -l for LMTP On occasions, when delivering to a list, deliver drops the connection to the MTA without sending a return code, despite the fact that it has delivered some of the mail.

The messages log has the following at the time when the connection is dropped Jun 13 13:27:20 mat.bath.ac.uk deliver[3128]: markdelivered: dbm_store: Bad file number Jun 13 13:27:20 mat.bath.ac.uk deliver[3128]: markdelivered: dbm_store: No such file or directory Does anyone know what is causing this?
