Knut Anders Hatlen updated DERBY-4294:
--------------------------------------
I think you got the the digits right, but the total size of the CLOBs is 24MB,
so they may exhaust a small heap if they for some reason aren't freed when
moving to the next row.
For the record, I didn't see the OOME when I tested with default heap settings
on JDK 1.6.0_13 on OpenSolaris, but I did see it when reduced the heap size to
64 MB (-Xmx64M).
