Search Again: OT: can''t capture debug info From: andrew Date: Saturday, September 1, 2001 Time: 10:45:39 am Hi All: I have QDNS 3.5 running on a 7300/200/64/2gig OS 9.1 QDNS has 8-meg ram allocated, no other apps are running on it. I have installed MacsBug 6.6.3 I have a Win2K server that's sending out an email list with about 37K names in it. The QDNS server is defined in WinDoze's TCP/IP prefs, so it's resolving the email addresses. The SMTP service on the Windoze box is throttled back to 16 outgoing connections. If I send out a test distribution to 4,000 names, I see the DNS being queried to resolve each domain. As the Win2K box churns through the list (about 10 minutes), I can watch the free memory in the QDNS window drop down to 100K and then shoot back up to 1.5 meg before descending down again. I also observe the "outstanding" and "queries per second" alternating between 0 & 8 during this period. The list completes and all is well. If I try to send the 37K list, somewhere about midway through QDNS crashes and the MacsBug window comes up. However at this point the keyboard is unresponsive so I can't type in StdLog or any other command into the debugger to capture the crash. The debugger shows "QDNS...." at the top of the hex code on the left side of the debug window. I can power-cycle the mac from the keyboard but nothing else, like CapsLock, works. I've had this problem with a number of different versions of QDNS from 2.2 up on several different boxes (7100/7250/7300-180) running OS 8.6 and 9.1 and it happens every time with different lists of this size. It happens both with IIS 4 and IIS 5 SMTP service, and the higher the number of outgoing connections the faster the DNS crashes. I'm trying to capture a debug log but can't...has anyone else experienced this? Is there a way to set MacsBug to dump a log automatically? TIA, Andrew Kagan
