Sorry for the noise. Seems this was related to some starman processes
which were in some strange state. Once I cleaned up all processes
using port 5000 (checking netstat -anp | grep 5000), this is no longer
a problem.

No worries, thanks for letting us know.

Hi Oliver,
I'm running everything on the same host, a VM so I don't upset our
production server. It seems to be something I can reproduce. I've just
rebuilt the VM so I can try again. It does seem to be the case that some
devices are not contacted by the scheduler but there's no problem using the
CLI. It isn't entirely reliable. I've noticed after many attempts the
scheduler will sometimes work. In production we have switches that have
been in place several months and have never been discovered. In these cases
the upstream switch has been discovered, LLDP is running so there's no
obvious reason why Netdisco hasn't got any further.
Happy to run any diagnostics I can that might be helpful.
Matthew

One quick update on this...
I've tried increasing the snmp timeout and this doesn't appear to have
improved things. I'm still finding plenty of devices that fail from the
scheduler but will work with CLI discover.
