Peter Schuebl commented on JBMESSAGING-1139:
--------------------------------------------

I have a similar issue.
JBAS 4.2.1 with MySQL - non clustered
JBM 1.4.0.SP1

Queue setup:

<mbean code="org.jboss.jms.server.destination.QueueService" name="jboss.messaging.destination:service=Queue,name=testQueue"       xmbean-dd="xmdesc/Queue-xmbean.xml">
      <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends>
      <depends>jboss.messaging:service=PostOffice</depends>
      <attribute name="FullSize">20</attribute>
      <attribute name="PageSize">5</attribute>
      <attribute name="DownCacheSize">5</attribute>
</mbean>

The queue is consumed by a bridge (installed on the local server)  which forwards to a remote server.
After sending about 50 (of 200) messages I disconnect the remote server from the network.

All the messages get sent to the local queue.
I shut down JBAS and start it again.

I than get an Exception:
Reason: java.lang.IllegalStateException: Cannot load channel 3 since the fullSize parameter is too small to load  all the required references, fullSize needs to be at least 151 it is currently 20

I tried the same with a second queue (identical setup, name is testQueue1) without a consumer
=> everything works fine there.

- I changed the FullSize of testQueue to 200 and restarted
=> startup worked fine and all messages delivered to the remote queue

- I changed the value back to 20 and restarted 
- disconnected the remote server from the network
- sent all 200 messages with the remote server unavailable
- shut down the local JBAS
- start it up again
=> all the queues start up correctly
- connect the remote server
- all messages are delivered

I don't know if it's the same issue.
The messages are MapMessages containing a byte[] with about 370kB

Is there any other information needed?

> JDK: Sun 1.5.0 Update 12 / 13
> JBAS: 4.2.1.GA (Non-Clustered)

> PRECONDITIONS:
>  A non-clustered fresh installation of JBM 1.4.0.SP1 in a JBAS 4.2.1.GA with PostgreSQL 8.2.4.
> WORKFLOW:
>  1.- Install JBAS 4.2.1 with PostgresSQL in a Non-Clustered environment
>  2.- Inslall JBM 1.4.0.SP1
>  3.- Startup JBAS with JBM.
>  4.- Send 200100 messages (1K each one) to '/queue/testQueue'.
>  5.- Stop the AS
>  6.- Startup the AS.
> POSTCONDITIONS:
>  There are 200100 message references in jbm_msg_ref with page_ord = null (100 belongs to unflushed downCache).
> When you try to boot AS it says: "Cannot load channel x since the fullSize parameter is too small to 
> load  all the required references, fullSize needs to be at least 200100 it is currently 200000".
> This is done (it seems) becouse when I shutdown the server the downCache is not flushed.
