             Bug #: 29208
           Summary: Extreme high CPU usage from unknown hang
           Product: Wine
           Version: 1.3.33
          Platform: x86-64
        OS/Version: Mac OS X
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: me at haravikk.com
    Classification: Unclassified


I'm sorry that this bug is unfortunately going to be very vague, as I haven't
been able to isolate a particular cause. The program I was running is also
currently under non-disclosure, but I don't believe the program itself to be at
fault, as I can run it fine under emulation or by booting into Windows.

Anyway, the program in question is an MMO similar to WoW, with an
auto-download/patcher tool. Having completed download, it should be able to
simply display play options, however, it instead hangs unexpectedly.

More unusually, WINE will then proceed to engage in extreme CPU utilisation; my
particular machine is 8-cores, but WINE was being reported with an over 1200%
utilisation!

I've no idea what it was doing, however, since I wasn't sure what to do used
Mac OS X's spindump Terminal command to capture a stack trace, which may
hopefully shed some light on the issue. If there is a more specific test that I
can perform, then please do let me know and I'll gladly perform it! The
attached spindump has the application name [redacted], if the issue still
exists after release I'll return with an updated log and information.

Anyway, hopefully analysis of the spindump gives some clues as to the cause of
the lockup/high CPU utilisation. The issue occurs every time, though I'm afraid
that may not be much use without the program to test!
