What does a Kernel Error 4 mean? I'm getting this
running 64 bit Exim. Just trying to track it down and
wondering what an "Error 4" is?

Thanks in Advance

Probably:

#define EINTR            4      /* Interrupted system call */

EINTR should be a non-fatal error; the fact that Exim reports it as an 
error probably indicates an Exim bug.

Of course, it could mean something completely different.

Interrupted system call?
See /usr/include/asm/errno.h. Generally, the kernel
errors are the negative of the user-mode errno values.

No, there is also

	"%s%s[%d]: segfault at %lx ip %08lx sp %08lx error %lx",

and an error code of 4 indicates PF_USER.
That is why it is *important* to provide an *exact* error message
and not just some hear-and-tell number.
