Hi,
how do I troubleshoot postgres? It simply won't start any more. I cannot login, not locally nor remotely. I tried a
coupleof things without success.
bash-3.2$ ps -Ac | egrep postgres
bash-3.2$ /Library/PostgreSQL/9.1/bin/pg_ctl start -D /Library/PostgreSQL/9.1/data -l postgres.log
pg_ctl: another server might be running; trying to start server anyway
server starting
bash-3.2$ /Library/PostgreSQL/9.1/bin/pg_ctl start -D /Library/PostgreSQL/9.1/data -l postgres.log
pg_ctl: another server might be running; trying to start server anyway
server starting
bash-3.2$ /Library/PostgreSQL/9.1/bin/pg_ctl start -D /Library/PostgreSQL/9.1/data -l postgres.log
pg_ctl: another server might be running; trying to start server anyway
server starting
bash-3.2$ ps -Ac | egrep postgres
So sure enough that process claimed to might be starting does not end up being a process. Where do I look for what's
actuallygoing on?
This is the log output:
04.06.12 00:26:29,792 com.edb.launchd.postgresql-9.1: If the request size is already small, it's possible that it
isless than your kernel's SHMMIN parameter, in which case raising the request size or reconfiguring SHMMIN is called
for.
04.06.12 00:26:29,792 com.edb.launchd.postgresql-9.1: The PostgreSQL documentation contains more information about
sharedmemory configuration.
04.06.12 00:26:29,793 com.apple.launchd: (com.edb.launchd.postgresql-9.1[1260]) Exited with code: 1
04.06.12 00:26:29,793 com.apple.launchd: (com.edb.launchd.postgresql-9.1) Throttling respawn: Will start in 10 seconds
04.06.12 00:26:30,000 kernel: nstat_lookup_entry failed: 2
It respawns every ten seconds and fails. Now this installation has been running for a few weeks now without a hiccup. I
triedto enable remote login, I might have screwed up the pg_hba.conf file. So I copied the same file from an
installationof another server I have on which things are running ok. I restarted but it continues to throw up those
respawnmessages and shared mem segmets stuff.
I changed the sysctl.conf file, but this neither made a difference. This unit has loads of memory....actually the
messagesseem to be rather bogus. Also, it worked fine, I didn't change the sysctl file before, it seems silly to assume
thatit just changes itself out of the blue and stops working. I installed nothing, there is no source I can assume to
havedone so. What can I do to make this server working again?
Thanks
