  I just got bitten by this also.  It prevented logins, as rlogin
would die as soon as it saw a non-NULL first character.  :(  And
ssh is apparently hosed, and we don't use telnet (too
insecure!).  Unfortunately, I killed and restarted inetd before
I saw the above.

  Interestingly, sshd appears to have gotten hosed at the same time:
Oct 23 19:31:15 sim1 sshd[8903]: fatal: xmalloc: out of memory (allocating 1073688827 bytes)

  Could this be related, or just pure coincidence?  I'll keep
that sshd running for a while...  This is all in
3.0-19980804-SNAP, BTW.
