Is probably that the cause of this behavior are many many dead tuples in the table.?

Asunto: Timeout error on pgstat
I have a lot (maybe 1 every 10 seconds) of this error WARNING: pgstat wait timeout
Also this
ERROR: canceling autovacuum task
In the pg_stat_activity show an autovacuum process over a very used table that runs about 1 hour and then this vacuum is cancelled (according to log)
I have Postgres 9.0.3 on a windows 2008 R2 running for about 1 year in same conditions, but this error is occurring about 1 week ago.
Thanks!!
