Thanks, I'll try it on my development environment. I tried some 8
version and application crashed.<br>

<pre wrap="">- Solaris 9
- Sun Cluster 3.1.0

About 3 times each week, the check_pgs function of the SUNWscPostgreSQL
bin/functios file, stops my Postgres database.
I enabled the cluster's monitor logs (DEBUG=ALL on etc/config) and found it
complains about a time out when manipulating the tables of the Postgres user
used for the cluster to test the health of the DB server.

The command it throws is this:

/usr/bin/su - postgres -c /usr/bin/env
LD_LIBRARY_PATH=/usr/local/lib:/usr/local/pgsql/lib /usr/bin/env
PGPASSWORD=XXXX /usr/bin/env PGDATA=/postgres/data /usr/bin/env PGPORT=5432
/usr/local/pgsql/bin/psql -d sc3_test_database -U scuser -c "truncate
sc3_table;insert into sc3_table (sccol) values('hello im there');select *
from sc3_table" &gt; /tmp/postgres_server-postgres-tbl-out 2&gt;
/tmp/postgres_server-postgres-tbl-err

A minute after the timeout occurs. Postgres.log doesn't show anything (I
dont log SQL instructions)

Are there any errors in the logs?

Postgres doesn't show any log (I'm logging only connections)<br>
Cluster says that the service is broken.<br>
And SUNWscPostgreSQL says:<br>
<br>
15:45:47 The probe command &lt;/opt/SUNWscPostgreSQL/bin/control_pgs -R
postgres_server -G postgres_rg -P /postgres/data/postgres.conf.cluster
probe&gt; timed out<br>
15:45:47 Restarting the resource postgres_server.<br>
