Comment 1 mishadmitriev 2005-04-21 07:17:16 UTC 
Now that we have released the Milestone 6 release of the Profiler, I would
suggest the user who originally reported the problem to download it and check if
the problem still exists. There is a chance that it has gone away; otherwise we
will hopefully get better/more up to date diagnostics.

Regards,

Misha
Comment 2 mishadmitriev 2005-04-27 05:19:22 UTC 
If this issue is not confirmed within a week or so, I would be inclined to close
it. We fixed a number of profiler engine related problems in M6, and this could
well be a manifestation of one of them.
Comment 3 mishadmitriev 2005-05-04 02:15:09 UTC 
Closing this issue for now as not confirmed/not reproducible.
Comment 4 ehucka 2006-10-09 12:08:29 UTC 
Verification of old issues.
Comment 5 Alexander Kouznetsov 2007-02-12 22:24:07 UTC 
Closing old issues.
