Page-size should be ignored on blocking. If the pageSize is configured beyond or the same as max-size, the constructor will throw an exception what could cause collateral damage since some state will be left unfilled.
The user has initially described this issue.
I have journal-file-size set to 10 Mb and max-size-bytes set 10 Mb, with a address policy of BLOCK. When my sendMailQueue reaches its limit a deadlock occurs. This is further emphasized in the JBossAS Forum reference.
Here's a snippet from jstack after HornetQ crashes.
