My problem is that the OnLine daemon dies abruptly. When this happens I enter the DBMonitor and restarts the system or issue a tbinit command 17:37:27 INFORMIX-OnLine Stopped Thu Mar 5 17:37:30 1992 17:37:30 INFORMIX-OnLine Initialized -- Shared Memory Initialized 17:37:30 Physical Recovery Started 17:37:30 Checkpoint Completed 17:37:30 Physical Recovery Complete: 0 Pages Restored 17:37:30 Logical Recovery Complete: 0 Committed, 0 Rolled Back 17:37:31 On-Line Mode 17:37:35 Process Aborted Abnormally: pid=-331 user=220 us=300010d0 flags=20001 <- this line indicates that the daemon has died, but I don'tknow what the flags mean and how to recover from my problem.
