It's a wonder it's not completely smoked. It did, which was part of the problem. From the comments made by Erik and Mark, the poor thing simply couldn't handle the I/O load presented by 30+ FTP sessions (I seem to remember the phrase "5 logins a minute"...), and A/UX crashed when some of its kernel tables overflowed (for you UNIX kernel hackers out there, I believe it was the callout table). Mark & Erik then scurried around to find an FTP server patch that would limit the number of simultaneous sessions, which would at least fix the symptom. I'd just like to throw in a couple observations, based on watching them try and do this while the WWDC was going on (and where they both had "official duties" to take care of at the same time): 1. Getting System 7.0 onto ftp.apple.com and available to the Internet seemed to be a large personal priority to the people involved, especially in the face of all of the "pre-emptive" complaints from people who decided that it wasn't going to happen. 2. They spent a lot of time and energy running between San Jose and Cupertino in order to get things fixed as quickly as possible, in between live DTS consultations, setting up the networking for the ATG demo (which involved live T1 speed connections to the Apple Cray and NCSA, for those of you who weren't there), not to mention the occasional break for meals or sleep. Personally, I was quite impressed. -- Amanda Walker amanda@visix.com Visix Software Inc. ...!uunet!visix!amanda -- "Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much because they live in the gray twilight that knows not victory or defeat." -- Theodore Roosevelt
