Hi,
Where running an app on tomcat built with Turbine and Torque and with a Mysql database.
Where using the SharedPoolDataSourceFactory to manage the connection pool to the database.
And there seems to be a problem on how this is beeing used, after uppgrading to Torque 3.1.1
the app would only run for aprox 5 minutes and then it would "stall". The problem seemed to be
that the pool was not being reused. This was with the testOnBorrow option enabled.
What sorted our problem out was using the minEvictableIdleTimeMillis option, now the app
has been up and running for servral days but it seems that some times i can take up to 40sec to
access the app if now current connection to the database is open.
Wich is a bit strange when our Mysql database shows that there are 5 idle connection.
And Torque still wants to open a new one and disgards the old.
Any ides?
Best regards Christian Bach
