cfarm210 is very slow

[Denis Ovsienko]

Hello.

My first attempt to log into cfarm210 today failed after several
minutes:

$ ssh cfarm210
Last login: Sat Jan 17 14:03:14 2026 from 129.151.92.78
Connection to cfarm210.cfarm.net closed.

The second time I was watching "ssh -v", which also took several
minutes, but eventually succeeded.  From the rate of the messages it
looked as if everything was consistently slow, rather than a particular
step.

Once logged in, the load average (1.52) didn't explain it, but disk
access was unusually slow when I ran "autoconf --version", then "find
/usr/local/" would print some lines quickly and stop for a while, then
resume, then stop again and so on.  So this could be either a failing
disk, as was the case in August 2024 with cfarm211, or sshd trying to
consume more entropy than the host can provide (if you temporarily
point it to /dev/urandom instead of /dev/random and the SSH delays
disappear, that's the case).

Anyway, the thing I was looking for on cfarm210 in the first place is
the Autoconf version, and it is 2.72.  Would it be difficult to have the
same or at least 2.71 in the following Buildbot builds?
