While using apt to update pidentd, I got the following error:
Unpacking replacement pidentd ...
E: Sub-process /usr/bin/dpkg received a segmentation fault.
I then retried the install, and this time the process hung writing to
a file.
I tried to ls in the directory that the file was hung in, no output of
data. Attemping to strace the process results in the strace process
hanging.
I've had some squirly stuff happen recently (one file system gave IO
errors until I ran xfs_repair). I think it might be time to boot from
recovery and xfs_repair everything... Maybe...
