Dag H. Wanvik commented on DERBY-5545:
--------------------------------------

John, thanks, I now see you used rollback(sp), not plain rollback(). I'll have a look to see
why rollback(sp) closes the first result set.

> Im seeing this error occur after loading alot of data into the Database. I can confirm
that autocommit is set to off, and that it occurs on calling  rs.next() immediatlely after
running a query and assigning to  resultset rs. The cdoe is called many times (250,000) and
usually works, then suddenly it starts going wrong, I also using c3po database pooling. Im
wondering if the problem is linked to memory consumption although I have no OutOfMemoryError
occurring

autocommit is OFF.
