After running with debugging at level 2, I saw that the script died at
00:57:35. Attached is the log from that time. I noticed specifically the
following lines:
Apr 9 00:57:35 MYSERVER postgres[7881]: [511892-1] LOG: disconnection:
session time: 9:33:45.60 user=dbuser database=mydb host=[local] port=
Apr 9 00:57:35 MYSERVER postgres[7874]: [13-1] DEBUG: server process (PID
7881) exited with exit code 0
Apr 9 00:57:35 MYSERVER postgres[7874]: [14-1] DEBUG: forked new backend,
pid=10009 socket=7
I don't see those lines at all before the problems begin, but I notice them
very often afterwards. Would I see the memory leak in the postgres
footprint? I will attempt to monitor the server's memory usage. Any other
debugging tips?
Thanks,
Frank
