Weblogic 6.1 sp1 jdbc connection to SQL Srv 7; receiving resources not available

Question

We've been running some load balancing testing on our website and at the high end
of the number of concurrent users, we begin to receive "QLException: java.sql.SQLException:
weblogic.common.ResourceException: No resources available" this is usually around
the 40 concurrent user mark. I've set the max JDBC connections to around 50,
initial connections to 20, capacity increment to 2 and the shrink period to 1
minute (though we've had that at 10, 15, and 59 minutes)...looking for suggestions
on problems. Currently using wblogic.jdbc.mssqlserver4.Driver and weblogicis
running on Linux

to always close a pool connection regardless of any exception, by the end of every user
request, then you should need only as many connections in the pool as there are execute
threads in the server. Do you have more than 50 execute threads?
