   The DOS version (2.0a in particular) does not appear to be burdened by 
this timer issue.   We have had DOS-based JNOS nodes run for in some cases 
HUNDREDS of days and NOT shown any signs of problems.   They continue to 
show sane uptimes, the beacons go out every 1900 seconds, the SMTP timer 
values continue to count normally.   Never a glitch.

   Can't say I have any data regarding NetROM timers and EXPIRE or any 
timers related to Heirarchical forwarding -- as we don't use any of them.  
But all other functions and timers have never showed any issues.  It is 
not, and it has not been, uncommon to run JNOS nodes unattended for many 
many months on end without reboot.  This *may* be a recent discovery of a 
fairly recent bug.  Do Linux-based nodes *REALLY* not stay up long enough 
to have noticed this, if it has been in the code for a long time???

   This does make me wonder - if the code base is the same DOS -vs- Linux, 
then is the compiler doing something different when setting up these 
counters??  Compilers have been known to have quirks...

   Thanks for your fine work, Maiko :)
