A crash caused the loss of messages POP3 was retrieving from
DOS.  The message that caused the crash was huge, so my guess
was that the disk cache interrupted the network.  Anyway, I
decided to take seriously my disk cache documentations saying
it "needs to be installed AFTER the . . . NETWORK drivers".

My disk cache does not have an unload option, so I've revised
my network swapping batch file to use the 4DOS REBOOT command
with an environment variable, normally set in config.sys as an
option to load the TCP/IP, written and then read after reboot:

In SWAPNET.BAT:

     echo ldtcp=y >! c:\boot.dat
     reboot

In AUTOEXEC.BAT:

     set /r c:\boot.dat >& nul
     del /q c:\boot.dat >& nul

As I wrote in my earlier post, swapping network stacks that
had been loaded after the disk cache and without rebooting
seem to work well for years.  I'm just not doing it that way
anymore.
