Subject [jira] Commented: (DERBY-260) Derby is not stable on multiprocessor or Hyperthreating architectures.

Sunitha Kambhampati commented on DERBY-260:
-------------------------------------------

I have run some simple tests on a 1cpu (linux machine) with hyperthreading enabled and once
on a 2cpu (Intel Xeon) win2k machine with hyperthreading enabled and it worked fine. 

Can you provide more details on what issues you noticed. That would really help to resolve
this issue.

> Hello,
> I am using IBM Cloudscape Version 10.0 with Hibernate and it works great. But at the
time I was deploying my project on a target with a Hyperthreating CPU things went wrong (database
very unstable). It seems that Cloudscape is not functioning on multiprocessor or Hyperthreating
architectures. Has anyone some more information?
