procmail problem

[Adam D. McKenna]

Sorry to post is  here, but I am getting tons of messages in my logs that look like 
this:

status: local 10/10 remote 4/20
delivery 64: deferral: 
procmail:_Out_of_memory/buffer_0:_"13739"/buffer_1:_""/preline:_fatal:_unable_to_copy_input:_broken_pipe/

There is over 200 megs of memory free, so I don't know why it would be out of memory.  
I checked the queue, and there aren't any messages larger than 200 megs..
