Hi all -
We are running postgres 9.0 ( 32 bit ) + postgis 1.5.2 on Solaris Sparc M5000 with 64GB . Recently we are getting CPU utilitzation to 99% .
In the config file
shared_buffers=2GB.
work_mem = 128MB
effective_cache_size=48GB
maintaince_work_mem= 500MB
max_connections = 300
When the CPU spikes happens, when I look at the pg_stat_activity log, the queries where current_query not like '%<IDLE>%' are between 100-110.
Do you think , I have to reduce the effective_cache and work_mem for this?
Thanks for your help.
