Hi,
I am developing a server using AsyncSocket/CFSocket wich is working
fine with only exception, that it freezes in the acceptor thread in a
call to CFWriteStreamOpen after having replied about 300-5000
requests. Sometimes it answers 100.000 requests without a problem but
50% of the time it freezes after 500 requests.
The stack trace of the frozen acceptor thread looks like this:
#0 0xffff85d8 in ___spin_lock_relinquish () at /System/Library/

Has anybody observed a similar behavior with CFSocket does anybody
know a way to get around this?
I am running 10.4.3.
Cheers
Frank
