On a Digital dual PII/32MB RAM/8GB SCSI
running the same query 45 times I get:

and am going to terminate your database system connection and exit.
May 6 09:23:09 digital logger: ^IPlease reconnect to the database system
and repeat your query.
This kills my sistem.
Increasing the memory to 96MB didn't work it out.
In real life I expect more than 45 queries simultaneously.
What can I do ?
TIA
