If you set your history file to contain only 1000 events, does that fix 
the issue.
from the tcsh man page:

history The first word indicates the number of history events to  save.
               The optional second word (+) indicates the format in 
which his-
               tory is printed; if not given,  `%h\t%T\t%R\n'  is  
used.   The
               format  sequences  are  described  below under prompt; 
note the
               variable meaning of `%R'.  Set to `100' by default.
