This symptom sounds suspiciously like something is hitting a limit.
Max open sockets, max open files, max file length. But there is
nothing that you've posted that makes me believe that is what is
happening. Could it be that the second server is limiting the
simultaneous number of connections from the front end server? I
assume that exim doesn't log anything in the panic log.
The consistency with which it does this on one account definitely
means something. If you hexdump the password file, do they have
different line-endings? Extraneous spaces? If you are saying that
the files are identical with the same md5sum, it's likely that this
has no bearing on it. (Assuming that the two are the same OS, using
the same version of exim, using an identical file, etc).
