We had problem reported to support where a customer was unable to create new Pagesetup without first deleting one. If they did then they got a kernel panic on the Mac. They sent the database to us and sure enough we were able to crash both a Power PC and an Intel Mac running the latest 10.4.9 OS. After crashing a few times we managed to trace it down to a bug in the OS.
It turns out that there appears to be a limit in the number of Published Appletalk Printers that the OS can handle which is 63 devices. (Pagesetups in our case). The customer was duplicating an existing setup which was already published (number 63) and when they saved after a short time as the device publishes the Mac crashes.
Not a lot we can do about this one but recommend when running your server on a Mac you have no more than 63 Pagesetups published at any one time. Please note that this is Pagesetups that are Published Appletalk devices. There is no limit to the number of Pagesetups that can be created (well there is, but it’s so mind bogglingly big you’ll never get there). It has been reported to Apple. Drop folders are not affected by this.

Recently I have been asked the question: “When does the pagesetup pool decide which pagesetup the job will process on ?”
The answer is pretty simple. As the job is about to start imaging, the server inspects the pagesetup pool configuration and the current job queue. It then assigns an appropriate pagesetup to the job. By making this decision as late as possible we ensure that the load balancing is more responsive to changing conditions such as a printer that has gone offline or ran out of paper.
