[comp.sys.apple] G/OS system error

SASQUATCH@ALBION.BITNET ("Kevin Lepard, 629-1827", 517) (09/30/89)

I've just started using GS/OS System Disk 5.0, and I've been seeing the
following:

GS/OS System Error

Address $02D19D         LC bank = $0
Error Code: $0002

I also saw address $00A516 once.

This usually (but not always, unfortunately) seems to occur when launching
a P8 program from ProSEL-16 7.8

I'm running a //GS w 1.25 Meg, Rom 01 with the minimum and maximum RAM
disk settings both at 256K.

Does anyone know what this is trying to tell me?  Also, does anyone know
of a _Beneath Apple GS/OS_ or equivalent kind of book?  My student's budget
doest have space in it for the plethora of apple reference manuals.

Last thing:  does anyone know of a CDA that will change the slots from
your card to modem port without having to reboot?  I need to switch between
my modem in slot 2 and the modem port (for xfering data between computers)
and rebooting all the time is inconvenient.

Thanks in advance.

I can't tell what this is without knowing more about your system--$02D19D is
memory that's managed by the memory manager, and what's there depends on what
drivers, FSTs, desk accessories, and setup files are installed in your system
and what order they're in.  If you can use Memory Peeker or whatever to find
the memory block containing $02D19D on your system, and give me all the info
about that block (ID, size, starting address), there's a fair chance I can
figure out what's happening.

Now *that* one I recognize.  It's caused by GS/OS's out-of-memory-queue routine
trying to dispose of the cache when the memory is needed by something else.
Under 5.0, if you have just the wrong amount of stuff in the cache, you get
that fatal error.  System Software 5.0.2 does not have this problem.

Such CDAs exist, but you may make GS/OS stop being your friend:  it
generates a character device driver for your serial port.
