Tiago R. Espinha commented on DERBY-3574:
-----------------------------------------

Ok I have a problem.

I ran the command that Kathey posted (without the -D switch and with -Xmx1024M 
since it gave out of memory with just 512MiB) and I got a stackload of error 
lines after a few hours of running. Here's what it said in the end:

FAILURES!!!
Tests run: 8010,  Failures: 1,  Errors: 8

Somehow I get the feeling that this is still a memory issue. I'm running the 
tests in a Virtual Machine running Ubuntu 7.10 with just 1GiB of RAM, and after 
a while, java is using all the RAM and has entered the swap file. Should I 
discard the VM and run it all natively on XP where I have 2GiB of RAM?

> See attached program TestLobLength for repro with commit.  If you comment out
