I'm running Postgres 8.1 on a CentOS 5 system with 4 GB of RAM. Whenever I set
shared_buffers above 320 MB, it won't run.
SHMMAX and it's at 4294967295 which is the max allowed for a 32-bit/4 GB system. Below are some of the other memory related settings:
max_connections = 225 shared_buffers = 327680 work_mem = 524288 max_fsm_pages = 500000 max_fsm_relations = 10000
Any suggestions on what could improve this?
