thx for your reply. so we use only the maxActive declared in OJB.properties. in the repository.xml we dont use the connection-pool elements.

when i have a quick look it seems to be about the broker pool and not the connection pool. Check your OJB.properties and set maxActive to the same value as maxActive of the connection pool settings in repository_database.xml. I am not sure about it but your problem happened to me once this way and it was solved by doing as i suggest. regards, Dennis 2006/10/26, Marwane <[EMAIL PROTECTED]>: > hi > we have a web application
