This is a summary of all of the answers I received about my "silo
overflow" message. Thanks to all who responded -- the list is too
long to mention everyone, but you all know who you are.
Little did I know when I posted my 2 questions that they are very
likely related! Basically, a silo overflow message occurs when a
serial port is generating more input than it can handle. It happens
when input occurs and no process is reading it from the queue.
The message "REPEATED LOGIN FAILURES on ttyd0 ..." seemed to be
generated as a result of improper configuration of the modem. As
these messages were appearing every few minutes on the console, it
apparently caused the overflow described above.
The changes I made were setting the parameter with eeprom
ttya-ignore-cd=false
and turning echo off at the modem.
I *think* the problem has been resolved. There have been no more
messages in the past few hours since I made the change. I have
included the original message for those that may benefit from it.
Thanks again!
