Re: DB Restart

We are running on 64 - bit.
Whenever the reserved memory in top command it crosses 3.9g it hangs.
If we try to kill process (using pg_cancel_backend()) it won't kill. At last either
we have to kill all process at OS level or we have to reboot the server. After rebooting
server everything worked perfectly fine. BTW we are using postgreSQL 8.3.2.

PID       USER      PR 
NI  VIRT   RES 
SHR S %CPU %MEM    TIME+  COMMAND

 4822 postgres  15   0
4045m 3.8g 3.8g S  0.7 12.1  
2:09.63 postgres: writer process

Thanks
Sam

Unless you are running on a 32-bit system you should be alright then.

What precisely is the problem? What do you mean by the DB "hangs"?
