Here is the explanation, derived from the escape code :

First, convert the escape code from decimal into hex

:calc -#19660693
-19660693, $FED4006B, %37665000153

Then, take first half and retrieve error code. It's left-padded with f's to
be interpreted as a 32-bit hex negative number.

:calc $fffffed4
-300, $FFFFFED4, %37777777324

Then, take right half and retrieve subsys (i.e. MPE module) which called the
error. Since this is a positive integer, there's no need to left-pad
anything.

:calc $6b
107, $6B, %153

Then retrieve the meaning of these two numbers

Without much of a surprise (see error text in Pat's message, appended
below), we get an error 3000 from subsys 107. Basically, that's an invalid
address for a memory location which address was supposed to belong in memory
cache. That's all I can say without more information.

Hope this helps, though it's not that much, I'm afraid.

I forwarded this on to our system manager, but thought I might get a faster
explanation from the list......
