Antoine commented on DBCP-379: ------------------------------ Hello, I also experience a similar issue: the number of connection rises above any limit set in the config. It causes a lot of trouble. It is probably in the case when a lot of connections are open at the same time. Please let me know if I can do something to help spot the issue. In my case, I use DBCP as part of Tomcat 6 with Grails and Hibernate. > number of connections created has crossed more than maxActive > -------------------------------------------------------------- > > Key: DBCP-379 > URL: https://issues.apache.org/jira/browse/DBCP-379 > Project: Commons Dbcp > Issue Type: Bug > Environment: OS:Red Hat Enterprise Linux AS release 4 (Nahant Update > 2) > uname:Linux 2.6.9-22.ELsmp #1 SMP Mon Sep 19 18:32:14 EDT 2005 i686 > vm_info: Java HotSpot(TM) Server VM (1.4.2_13-b06) for > linux-x86, built > on Oct 18 2006 09:55:11 by unknown with unknown compiler > Reporter: Bhaskar NA > > I found that when the minIdle is configured then during loads, common pool > creates more number of connections it will be greater than maxActive. > When I had following settings: > maxActive = 50 > maxIdle = 30 > minIdle=30 > factory=org.apache.commons.dbcp.BasicDataSourceFactory > maxWait=10000 > timeBetweenEvictionRunsMillis=900000 > numTestsPerEvictionRun=50 > minEvictableIdleTimeMillis=1800000 > testWhileIdle=true > testOnBorrow = true > validationQuery='select 1 from dual' > Number of connections in the pool went upto 121.
