Hello,

I'm using James 3.0-M3 with maildir. Everything works fine for one or
two days until I start having memory problems and I need to restart
James.
The problems begin with a long series of messages such as

WARN  04:46:27,928 | org.apache.activemq.broker.jmx.ManagedRegionBroker
| Failed to register MBean:
org.apache.activemq:BrokerName=james,Type=Subscription,persistentMode=Non-Durable,destinationType=Queue,destinationName=spool,clientId=ID_alice-58445-1306246275420-4_1,consumerId=ID_alice-58445-1306246275420-3_1_22_4524

and then 

DEBUG 04:51:11,445 | james.smtpserver | Unable to process request
java.lang.OutOfMemoryError: PermGen space

The CPU usage is over 100% and my only alternative is to restart James.
I tried to increase VM memory (at this time I have -Xms512m -Xmx1024m)
but the problem keeps coming back.
Does anyone have a suggestion to solve the problem?
Thanks in advance,


Nicola.
