On reviewing the Procmail logfile, I noticed that from time to time, an

No, formail doesn't have a limit on message size. You mentioned the
cause yourself: formail doesn't need anything other than the headers, so
it doesn't read anything else. For small messages this doesn't cause a
problem because there's enough room in various buffers that procmail is
still able to write the entire message to the pipe. But with large
messages the buffers fill up before the entire message has been written,
so procmail gets an error when trying to write to the pipe. The
solution is indeed to tell procmail to just send the headers through the
pipe (or alternatively, use a command that will read the entire
message).
