> OutOfMemory after redeploy services
> -----------------------------------
>
> Key: AXIS2-5233
> URL: https://issues.apache.org/jira/browse/AXIS2-5233
> Project: Axis2
> Issue Type: Bug
> Components: kernel
> Affects Versions: 1.6.1
> Reporter: Oleh
>
> We have OutOfMemory error after redeploy services.
> PROBLEM:
> Class org.apache.axis2.deployment.DeploymentEngine has scheduler.
> If (hotdeployment = true) we have startSearch in loadServices method.
> But we don't clean old scheduler in startSearch method !
> Old SchedulerTask has old RepositoryListener (old WSInfoList)
> Old WSInfoList has all old services !
> The scheduler starts thread as deamon.
> The Thread is running..running.....
> New deploy -> new Thread
> The Thread has old data (WSInfoList) and may be GC don't clear memory (Thread has link to data)
> We have result:OutOfMemory :(
> SOLUTION 1
> Fixed class org.apache.axis2.deployment.DeploymentEngine
> Method startSearch(RepositoryListener listener)
> Old Variant
> protected void startSearch(RepositoryListener listener) {
> scheduler = new Scheduler();
> scheduler.schedule(new SchedulerTask(listener), new DeploymentIterator());
> }
> Fix Variant
> protected void startSearch(RepositoryListener listener) {
> if (scheduler != null) {
> scheduler.cleanup(); // May be it is very important !!! : )
> }
> scheduler = new Scheduler();
> scheduler.schedule(new SchedulerTask(listener), new DeploymentIterator());
> }
> SOLUTION 2 (temp) - Disable Hot Deployment
> File axis2.xml
> <parameter name="hotdeployment">false</parameter>
