Disable/Enable behavior of Component Factory when under stre

I?m running some performance tests with Mediator and has taken a sequence and broken it down into smaller segments. The first sequence only contains a validation step and look as follows:



< !–{Name: ValidateDocument};{Notes: }–>





I now run some tests against this sequence, where my client has a single thread and is posting 1000 documents to Mediator. The first time I run the sequence everything works perfectly, but on the subsequent test runs I noticed that the average throughput in messages per second decreased dramatically. I also noticed in the Admin Console that there would be periods when no messages would come in from the client.

I then noticed that my Component Factory is disabled and then after a while enabled again. This is the output in my xbdhost.log file:

I?m running my component factory with the following settings:

Log Level: Error
Log File Size: 200
Log File Backups: 5
Security Preference: off
High Memory Mark: 90%
Low Memory Mark: 70%
JVM ?X Options: -Xms64m -Xmx128m

I?m pretty sure I?m not running out of memory. I went and increased the ?Xmx128m to ?Xmx256m, so me max heap size should be large enough to handle these documents. My document size is only 1675 bytes. What could be the cause of this behavior and what could I do to fix it?
