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.
