The debug output in cygserver is activated by giving the option `-d' to cygserver: $ /path/to/cygserver -d > I just saw a strange stuff : in sysv_sem.cc (cygserver) at end of semop > function (:done2 label), the mutex is released after waking up waiting > process, shouldn't it be the inverse ? No, the mtx_unlock is correct. If you're looking for bugs, they are very likely in the bsd_* files in cygserver. Even though the sysv_* files taken from FreeBSD are not proved to be 100% correct, there's a high probability that I produced the bug in some of the bsd emulation functions. msleep is a good candidate, FWIW. Any active debugging or tracking down the bug is highly appreciated, probably not only by me.
