Hi,
I'm running Postgres 7.3.2 and since a couple of week I can read in the log
 ( twice in a week ):

Apr  8 16:00:03 sdr2 postgres[16882]: [255913] DEBUG:  child process (pid
9081) was terminated by signal 11
Apr  8 16:00:03 sdr2 postgres[16882]: [255914] LOG:  server process (pid
9081) was terminated by signal 11
Apr  8 16:00:03 sdr2 postgres[16882]: [255915] LOG:  terminating any other
active server processes



This is all activity that was performed by the process 9081
( is always the same select that genereate the signal 11 ):

Signal 11 is SIGSEGV on Linux (and any POSIX UNIX, I believe), which
should terminate and dump core.  Do you have a corefile anywhere?
You could run a debugger on it and find out what happened.
