All the log file shows is:

----------  Mon 04 Jun 07, FastEcho 1.46; TOSS

+  7:21:47  AF.PKT from 1:138/389 to 1:382/33 (00FE, Type 2+)

It very well could be a memory issue since it is a dos program.  I set up a 
swap file, but am not sure what else to do.  I've got problems with fastecho 
and irex as well (described in those echo areas).  I'm thinking on dumping the 
whole system if I can't get this to work, but that would be depressing.
