From: wrw AT decisionism DOT com (Randy Watler) Subject: Question: concurrent users using gnu-win32 tools/shared_init? 6 Sep 1997 15:06:49 -0700 Approved: cygnus DOT gnu-win32 AT cygnus DOT com Distribution: cygnus Message-ID: <199709042157.PAA14911.cygnus.gnu-win32@plover.decisionism.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Original-To: GNU-Win32 AT cygnus DOT com Content-MD5: Ppb+y7ZMbZk3YXGLFshuZg== Original-Sender: owner-gnu-win32 AT cygnus DOT com We are currently using the gnu-win32 tools, (b17.1), to perform builds on a multi-processor NT server. When multiple users are logged into the machine via telnetd, (from Ataman TCP), and attempt to use most any of the cygwin tools simultaneously, they crash with the following message to the telnet session: (unknown) shared_init:CreateFileMappingA cygwin:terminating and with a generic "cannot read from address" terminal dialog. Looking at the source, we believe that these messages originate from winsup/shared.cc. It apparently tries to allocate shared memory with a security descriptor that allows 'all' access. Somehow this is failing when concurrent users perform this function? Is there some setup that we have blown or is this a known limitation? Thanks, Randy Watler - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
