Subject org.apache.derbyTesting.functionTests.suites.All is extremely CPU intensive!
Date Wed, 14 Feb 2007 22:17:00 GMT
Do anyone else see this?

I see this in all(?) test runs since the tinderbox test run on svn 507489.
( 
http://dbtg.thresher.com/derby/test/tinderbox_trunk16/jvm1.6/testing/Limited/testSummary-507489.html

)
That specific test run I aborted after ~6 hours.
(Test started ~11:29:52.655 GMT, killed ~17:27:23.428 GMT)

The duration of suites.All on this platform has been 42-46 minutes in 
the previous 4 successful runs.

CPU utilization now is close to 100%:
.. .. 97.0 ... java junit.textui.TestRunner 
org.apache.derbyTesting.functionTests.suites.All


In another test run 
http://dbtg.thresher.com/derby/test/trunk15/jvm1.5/testing/Limited/testSummary-507650.html

/ Linux-2.6.9-34.ELsmp_x86, suites.All finished in ~4 times the 
previously seen duration time.
