Things like this scare me[0], because they often indicate

sig11 is a segfault.  It's commonly seen where hardware
has gone marginal (esp. RAM).  See:


If the machine hasn't seen a kernel upgrade recently, it's
not likely that it knows how to report failing ECC RAM.

It may be that you have bad RAM, but it's also possible
that some other piece of hardware has gone flaky and is,
for example, drawing too much power for the rest of the
system to stay solid.

The ld-linux.so.2 errors are just because that half-library,
half-executable is required to load all other dynamically-
linked binaries.

    because of the number of poor unfortunate boxes I
    have seen r00t3d through the WU imapd.
