[ADMIN] PG shutdown itself?

[Lee Wu]

Greetings,   To best of my knowledge, nobody issued pg_ctl stop –m fast while we experienced PG was trying to shutdown unsuccessfully:   *** Everything seems normal before this point *** Mar  3 21:07:55 myhost postgres[630]: [24] LOG:  recycled transaction log file 00001ABC0000006D Mar  3 21:08:57 myhost postgres[5158]: [1] LOG:  fast shutdown request Mar  3 21:08:57 myhost postgres[5158]: [2] LOG:  aborting any active transactions Mar  3 21:08:57 myhost postgres[14292]: [1] FATAL:  This connection has been terminated by the administrator. *** A lot of “This connection has been terminated by the administrator.” taken out here *** Mar  3 21:08:57 myhost postgres[15912]: [3] FATAL:  The database system is shutting down *** A lot the same message as last line till  *** Mar  3 22:10:39 myhost postgres[1840]: [3] FATAL:  The database system is shutting down   Then I used “–m immediate”: Mar  3 22:10:39 myhost postgres[5158]: [3] LOG:  immediate shutdown request Mar  3 22:11:07 myhost postgres[1918]: [1] LOG:  database system was interrupted at 2005-03-03 21:08:53 MST Mar  3 22:11:07 myhost postgres[1918]: [2] LOG:  checkpoint record is at 1ABC/929DFCB4 Mar  3 22:11:07 myhost postgres[1918]: [3] LOG:  redo record is at 1ABC/9044F3B4; undo record is at 0/0; shutdown FALSE Mar  3 22:11:07 myhost postgres[1918]: [4] LOG:  next transaction id: 1090597972; next oid: 4231750970 Mar  3 22:11:07 myhost postgres[1918]: [5] LOG:  database system was not properly shut down; automatic recovery in progress Mar  3 22:11:07 myhost postgres[1918]: [6] LOG:  redo starts at 1ABC/9044F3B4 Mar  3 22:11:07 myhost postgres[1919]: [1] FATAL:  The database system is starting up *** PG was up after a lot of the above message ***   PG version is 7.3.2 on Red Hat Enterprise Linux ES release 3 (Taroon Update 4) I know it is old, but anyone can smell why PG shutdown itself?   Thank you,
