Subject [jira] [Commented] (DERBY-5638) intermittent test failure in test_05_ClobNegative when running full largedata._Suite; LobLimitsTestjava.sql.SQLException: Table/View 'BLOBTBL' already exists in Schema 'APP'.

Myrna van Lunteren commented on DERBY-5638:
-------------------------------------------

Some additional info.

I first started running this _Suite every night that there were changes (plus every Friday
regardless of changes) with trunk and ibm 1.6 in September of 2011.
It ran into a failure - ERROR 25502 - (An SQL data change is not permitted for a read-only
connection, user, or database) a disk space issue on December 7, 2011, and after that (extending
to Dec 8, 2011) the disk ran full. I cleaned that up, and tests ran fine again until 2/21/2012,
when the tests failed because of an issue with the Derby5624Test. After that, I first saw
this error (Table/View BLOBTBL already exists) on 2/22/2012. It seemed at the time this was
possibly related, but that does not make sense - the only change was adding of a new test,
and this test was afterwards getting skipped on linux.
To confirm, I have run the suite on an exact matching machine with 10.8 (and ibm1.6) and there
have been no failures.
I also ran the suite on a much slower 1 CPU machine with windows XP, and trunk, and there,
I have seen the test fail 4 out of 5 times (before old test results have clogged up my disk).

> Unfortunately, when this happens, there seems to be no 'fail' directory created. The
derby.log in the system directory looks very innocent (just some start up and shutting down
of the database), and the serverConsoleOutput.log only has the typical 'failed to find db
'wombat' messages'.
> Note, when this happens, the suite exits, so that instead of the expected 20 (or 21 on
windows, see DERBY-5624 for reason for skipping on Linux default installs with 1024 max open
files) we only get 15 (or 16) tests run - if the test doesn't fail it goes on to run the last
5 fixtures again for network server.
