Package: munin
Version: 2.0.25-1
Hi,
This feels like #464880 all over again :) You can easily change the cron
jobs and it generally works. However, as soon as any one of your nodes
croaks, everything basically grinds to a halt way too easily.

The problem is that there are several hardcoded timeout variables,
*independent* of the value you can pass via munin-update --timeout=N
/usr/share/perl5/Munin/Master/Node.pm:io_timeout = 120,
/usr/share/perl5/Munin/Master/ProcessManager.pm:worker_timeout = 180,
/usr/share/perl5/Munin/Master/ProcessManager.pm:timeout = 240,
So you *think* you set a timeout smaller than a minute, but actually the
socket read function waits for much longer than that.
Please make these configurable just like the other timeout is. TIA.
