Hi again,  (now with enters and spaces :) )

 

After 1 or 2 days of normal execution, the server hangs: I can't login by ssh or access to the web console (or any other application running on JBoss).

 

The log of JBoss just stop without any exception.  

 

This problem started when I configured the pool size of may MDB with the @Pool annotation. I have more than 50 MDBs.

 

Because of my performance problems (of throuput) I try to configure differents pool size on each MDBs.  

 

So, I'd configured \server\default\deploy\jca-jboss-beans.xml,  with 2048. And put diferents values on each MDB. 

 

          @ActivationConfigProperty(propertyName = "maxMessages", propertyValue = "1"),          

          @ActivationConfigProperty(propertyName = "maxSession", propertyValue = "50")})          

          @Pool (value=PoolDefaults.POOL_IMPLEMENTATION_STRICTMAX,maxSize=50,timeout=20000) 

 

The sum of the all maxSize is around 1000. 

I've no problem of database connection.  

I've no OutOfMemory exception.  

I've no exception on my logs.  

 

My server is running on a VirtualBox 4, with 8 processors (the host has 16)  with 6GB of RAM (the host has 16GB).   

 

I guess about a multithreading problem or a pool administration bug, but I can't found any solution.  

 

Can anybody help me? 

Thanks in advance. 

Martín
