Hi All, 

I am facing the below error when executing “VACCUM ANALYZE” on the several tables and also the entire PostgreSQL database hanging up and not responding.

WARNING:  worker took too long to start; cancelled

 I have disabled my AV and I have the modified the below parameters in my postgresql.conf file

• shared_buffer = 1024MB
• max_fsm_pages = 409600
• max_fsm_relations = 5000            

I am using PostgreSQL 8.3.5 on windows 32 bit machine.

Any help would be highly appreciated as this is kind of show stopper for me.
