Hi Tom,

I saw no vacuum log entries. After manually vacuum the database the load 
went down and the performance went back to normal.

After uncommenting #autovacuum = on and inserting track_counts = on 
autovacuum begun to work.

I had a brief look at the spacewalk setup scripts, nothing found so far.

When have a look to the db with 
I see the following error:

ERROR:  relation "pg_autovacuum" does not exist at character 157

In statement:

SELECT vacrelid, nspname, relname, enabled, vac_base_thresh, 
vac_scale_factor, anl_base_thresh, anl_scale_factor, vac_cost_delay, 
					FROM pg_autovacuum join pg_class on (oid=vacrelid) join 
pg_namespace on (oid=relnamespace) ORDER BY nspname, relname

The PostgreSQL packages have been installed from CentOS5, I'm going to 
try to reproduce this on RHEL5 tomorrow (if time allows me to do so)
