>      Project: Jetspeed
>         Type: Bug
>   Components: PSML, Registry
>     Versions: 1.6-dev
>  Environment: Windows servers (2000/2003) with hyperthreading CPUs (or multiple CPU)

> 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):
