[PATCH] Hyperthreading causes registry/PSML loading errors

• Key: JS1-526
• Type: Bug
• Status: Resolved
• Resolution: Fixed
• Priority: Blocker
• Assignee: Mark Orciuch
• Reporter: Bjorn Vidar Remme
• Component/s: PSML, Registry
• Affects Version/s: 1.6-dev
• Fix Version/s: 1.6

Description

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):
