Re: Assertion failed - tried to dispose a non read-only transaction

Hi Toby,

Sorry it's taken me this long to get back to you - busy as hell at the 
moment.

I haven't been able to devote much time to the problem as such, but have 
found that increasing the memory assigned to the JVM from its previous 
64Mb to 100Mb eliminates the problem.  All I can tell you at this stage 
is that the problem is very reproducible if I follow a certain pattern 
of queries/updates/inserts to my database, when running JVM assigned 
with 64Mb of RAM .  What the queries are, I haven't been able to find 
out yet; the calls are made from an application.  As soon as I can (no 
promises when :-) ) I'll email you a test case that reproduces the problem.

Thanks,
Nick
