Further info : Very high load average but no cpu utilization ?

Hi ,

i am sorry to bother you people again and again , but i guess this
is a bad patch for me which will soon pass on ;-)

my postmaster is running but most of the backeds are defunct ,
and on connecting get following error message:

$ psql -h 130.94.22.209  -U tradein  tradein_clients
psql: server closed the connection unexpectedly       This probably means the server terminated abnormally       before
orwhile processing the request. 
[rmallah@server rmallah]$


how do i bring down postmaster safetly?

ps output is as below.
