Hello, this is on Zope-2.1.1, with IIS When Zope dies through a request made with PCGI (such as when I shutdown the Zope process or restart it), pcgi-wrapper 'spins' (it consume all system resources, the system become unusable, and I can't even kill pcgi-wrapper - I had to reboot the computer), apparently waiting for Zope to release something. Here is what I read in pcgi-wrapper.c on line 893: /* Travel beyond this point requires calling the ReleaseMutex function. Fortunately, the Win32 mutex is automatically released when a process terminates, but we could still encounter a situation where the process is hung or stalled ... */ Am I in the "situation where the process is hung or stalled" ? Or is there a "magic" way to solve my problem. Please help. I have planned to go production next week but with that problem, I can't! Regards, Jephte CLAIN
