Cocerning the UNIBUS MAP REGISTER EXCEEDED crash that I previously described, another user has told me that they also experienced a similar crash, and that there is a problem with the LCDRIVER. Another user mentioned that they had thought that they saw a patch for the LCDRIVER in V4.5 that might be related to fixing the problem. I subsequently found that my spooler software that I was using was sending incorrect information via a QIO, and that caused the situation. Most users will probably not run into the problem.
