Hello, I downloaded and compiled the Mar 2, 2005 snapshot and compiled it with bsm auditing for solaris turned on. I've been noticing about a dozen or so of the following messages per day now. Not sure exactly what it is, or if it is a big issue. Mar 3 13:46:10 machine_name sshd[15298]: [ID 800047 auth.crit] fatal: mm_request_send: write If it matters it is running on solaris 8 sparc, with pretty current patches applied.

I suspect it's a connection that is disconnected without supplying a username, or which supplies a username but does not attempt any auth methods.

If the monitor has already shut down then sending the request will fail causing the error you're seeing. Please try the attached patch (which should apply on top of the previous patch). I'll attach the patch to bug #125 too. -- Darren Tucker (dtucker at zip.com.au) GPG key 8FF4FA69 / D9A3 86E9 7EEE AF4B B2D4 37C9 C982 80C7 8FF4 FA69 Good judgement comes with experience.
