[Bug 29208] New: Extreme high CPU usage from unknown hang

http://bugs.winehq.org/show_bug.cgi?id=29208

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: [e-mail]
        ReportedBy: [e-mail]
    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!

Other then high CPU does it affect your game in any other way?

It hangs completely; whatever WINE is doing it's utterly locked up, I have to
force the program closed to regain use of my machine. I can run the game
normally under emulation or by booting to Windows, but under WINE it won't work
at all, yet all I can think it should be doing is enabling the "Play" button,
as it gets passed the file-verification/download steps just fine.

I mean, it's entirely possible it is partly the fault of the game as well, but
I don't see why WINE's load should increase so dramatically, and can't figure
out what it's doing. Does the stack trace hold any clues?

First of all you are not using plain Wine but wineskin. We don't support any
3rd party Wine modifications here.

I don't believe Wineskin to be the problem; it's just a wrapper for WINE, no
different than installing WINE to a custom location yourself and launching it
appropriately. I've tried a standard WINE install (via Macports), but I have
exact same problem.

At a cursory glance the spindump looks no different, except that obviously the
path to WINE is different.

This is your friendly reminder that there has been no bug activity for 2 years.
Is this still an issue in current (1.7.7 or newer) wine? If so, please attach
the terminal output in 1.7.7 (see http://wiki.winehq.org/FAQ#get_log).
