And today's trick question...how do you send a break? :( I'm telnet'd into a Livingston Portmaster, with 'telnet -E' to disable the telnet break...I have DDB and DDB_UNATTENDED enabled and running right now, so if I can get this break issue working, then I'm all set for the next time if it happens :) > Anyway, I have a simple program that mmap()s a 1Gig file into memory, > madvise()s it that it will be doing random access.

Just to prepare myself, if/when I get that break to work...you just did a 'trace', or is there something else I'll want to do in DDB? Marc G.
