Category: JBossServer Group: None Status: Open Resolution: None Priority: 5 Submitted By: Jan Stolze (jstolze) Assigned to: Nobody/Anonymous (nobody) Summary: Memory leak in database access Initial Comment: Hello, I've discovered a memory leak in the Database access part of JBoss. I have performed the following test. 1. Request a database connection from the initial context. 2. Inserted, selected and deleted a record in a MSSQL Server database via JDBC. 3. close the connection. 4 repeat endlessly. After about 3 million repetitions an OutOfMemoryError occurs. I've started JBoss with a minimum and maximum heap size of 20 MB. This means that JBoss had 5 MB op heapspace free to perform the above test. I've measured this by requesting the freeMemory on the VM. I can exclude the MS SQLServer JDBC driver, because I have tested it in a seperate java program that does the exact same with the only difference that it doesn't use connection pooling. No memory leak appeared then. Another test I've performed is like the above, but I've only requested a database connection once from the inital context, no memory leak appeared. So I think it is in the connection pooling part of JBoss. Config props are: JBoss 3.0.3 JDK: Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_03-b03) Java HotSpot(TM) Client VM (build 1.3.1_03-b03, mixed mode) Platfrom: Windows 2000. JDBC Driver: MS SQL-Server JDBC driver ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=687809&group_id=22866 ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development
