Hello, we are currently evaluating JBossCache 1.2 and have run into serious and reproducable memory problems when stress testing the cache with a professional load tool (PureLoad). Something in the replication module is eating memory at an incredibly fast pace. After only minutes of testing the garbage collection is activated and a full garbage collect is performed after about 15 minutes. During garbage collection the entire JVM is not responding and in some cases automatically restarted by the Oracle Process Manager.
When testing with a legacy local cache solution the JVM uses about 150-200 MB of memory. Using the JBossCache in asynchronous replication mode the JVM steadily increases its memory up to about 500 MBs at which point a full gc is invoked (the allocated JVM memory is 512 MB). If replication is turned off and the JBossCache is only running as a local cache, the JVM memory usage is back to the normal level of 150-200 MB. Question: is there a known memory leak or memory management problem with JBossCache, and in that case what can be done to stabilize the memory consumption? Settings for the cache are: * Asynchronous replication (replAsync-service.xml out of the box with the suggested modification for windows, i.e. loopback = true). * no transactions (IsolationLevel.NONE) Settings for the test environment are: * Windows cluster with two W2K servers, 2 JVMs per server * JDK 1.4.2_05 * Application server is Oracle 9.0.3 AS * one database server (Oracle) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3866779#3866779 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3866779 ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
