As I recall, the appport stuff in Ubuntu is terrible ... I've seen it
take 40 minutes to write the crash dump to disk, during which the
database was "down". I don't know why it is so slow (it's a rather
silly python script that apparently processes the core dump one byte at
a time, and you can imagine that with a few gigabytes of shared memory
that takes a while). Anyway my recommendation was to *remove* that
stuff from the server and make sure the core file is saved by normal
means.
