Hello

I have pg_autovacuum running with the arguments: 

pg_autovacuum -D -s 120 -v 10000

the database is postgresql 8.0.0

Sometimes load average on server raises to 20 and it is almost impossible to
login via SSH

When I'm logging in finally, I see there is cpu usage: 6% and iowait 95%

ps ax | grep post gives me 

postgres: postgres db [local] VACUUM

Is there some solution to avoid such cases?
