at blowing up

[Scott Reading]

 I am posting this to comp.bugs.2bsd as well as seattle.general in the
 hopes that those of you local people with the Teltone Calldata systems
 running 2.9BSD might be warned/help.  

 I am using 'at' to remind me of future appointments (calendar won't
 fit on my 64k data/instr machine).  At will not schedule events into the
 next year.  I don't know whether its because its the turn of the century 
 or just the next year.  Not only that but when I scheduled 'at' to send
 me mail in January from a shell script that reschedules itself automatcally
 it got caught in some sort of loop and send me 488 pieces of mail before
 I noticed and aborted it.   Its not the shell script because it has been
 working correctly for several months.

 Any leads would be appreciated.

 Thanks,
 Scott
