Hi,
 
I see the following error as found in pg.log:
UTC4115FATAL:  the database system is in recovery mode
 
Actually that message was logged repeatedly for about 4 hours according to the logs (I don't have access to the system itself, just the logs).
 
Leading up to that error were the following in pg.log:
2011-03-28 10:44:06 UTC3609LOG:  checkpoints are occurring too frequently (11 seconds apart)
2011-03-28 10:44:06 UTC3609HINT:  Consider increasing the configuration parameter "checkpoint_segments".

In fact those last 3 lines are repeated over and over again repeatedly until "UTC4115FATAL:  the database system is in recovery mode" is logged for 4 hours. At some point, 4 hours later of course, it appears that the system recovers.
 
The Checkpoints Settings in postgresql.conf are commented out so I guess the defaults are being used:
#checkpoint_segments = 3                # in logfile segments, min 1, 16MB each
#checkpoint_timeout = 5min              # range 30s-1h
#checkpoint_warning = 30s               # 0 is off

 
That system where this was seen was using pgsql-8.2.6 on RHEL4.
 
Not sure if this is a known bug (or if it is a bug at all or something I can address using different configuration) but I thought I would post here first if any one might be familiar with this issue and suggest a possible solution. Any ideas?
 
Cheers,
Matt
