Hi Konstantin: About this link
http://commons.apache.org/proper/commons-dbcp/configuration.html If you have enabled "removeAbandoned" then it is possible that a connection is reclaimed by the pool because it is considered to be abandoned. This mechanism is triggered when (getNumIdle() < 2) and (getNumActive() > getMaxActive() - 3) I know that it's about DBCP , not JDBC Pool in Tomcat 7, but Do you know if it's the same mechanism ? In this case, this mechanism only is useful when pool is about to be exhausted, right ?
