Hyperthreading causes registry/PSML loading errors
--------------------------------------------------
Key: JS1-526
URL: http://nagoya.apache.org/jira/browse/JS1-526
Project: Jetspeed
Type: Bug
Components: PSML, Registry
Versions: 1.6-dev
Environment: Windows servers (2000/2003) with hyperthreading CPUs (or multiple
CPU)
Reporter: Bjorn Vidar Remme
Priority: Blocker
Running Jetspeed 1.6-dev (HEAD -> 2004-11-23) throws exceptions when reading
xreg & psml files if the system has more than more CPU (or hyperthreading).
This affects 1.6-dev only, 1.5 works perfectly.
After disabling hyperthreading Jetspeed-1.6 works perfectly (confirmed on three
different servers).
Where the problem occurs is a bit random, and is affected by the server load.
The problem seems to be associated with the classes 'LateCastorRegistryService'
and 'CastorPsmlManagerService'.
Please contact me for more information if needed.
Here is an example exception from the jetspeedservices log (not very
informative):
2004-11-24 11:27:34,656 [http-8080-Processor25] ERROR CastorPsmlManagerService
