[ic] interchange crashing?

[interch]

weve been experiencing a couple strange things with our installation of 
interchange.  It seems to be working well most of the time (its been up 
for the most part for a month now getting 6-8k hits).  But just this 
evening i noticed that one of the interchange processes was using 80-90% 
of the cpu.. and 86 MB memory.  Looking at the interchange error.log i 
found a bunch of lines like this (hundreds):

205.232.129.9 - - [29/October/2001:10:23:16 -0600] auto /cgi-
bin/auto/brands/menu/carcareaccessories.html Died in server spawn: Can't 
call method "new" on an undefined value at /usr/local/interchange/lib/Vend/
Data.pm line 674.
216.97.217.186 - - [29/October/2001:10:23:38 -0600] auto /cgi-
bin/auto/index.html Died in server spawn: Can't call method "new" on an 
undefined value at /usr/local/interchange/lib/Vend/Data.pm line 674.

and in the catalogs specific error.log the last few entries were something 
like this:

205.188.200.48 eiZdeF8z:nobody - [30/October/2001:18:26:01 -0600] auto

and i also noticed that off and on, some days it will have hundreds of 
entries in the same log with lines like this:

198.62.9.30 xb5rdVXq:nobody - [29/October/2001:10:23:30 -0600] auto

but for some reason none of those happened today, but we were loaded with 
them yesterday.  I dont know if this makes sense to anyone or if anyone 
has any bright ideas, but it would be much appreciated if i could tap all 
of your knowledge.
