Right.

Right - that's not currently possible. This has come up just recently
(on IRC iirc) and the idea was to introduce a global option that allows
to specify the max. waiting interval (currently, this is hardcoded to
one day, i.e. 86400 seconds).

Do you want to give that a try and provide a patch? Global options are
defined and handled in configfile.c, while error handling of read
callbacks is handled in plugin.c:plugin_read_thread ...

Cheers,
Sebastian
