You haven't provided much information on your installation but at a guess, you have something that is writing bad data to nagios.cmd. Do you have something submitting passive service checks? Have you mistakenly configured some application to write to nagios.cmd when it shouldn't be? I would have expected something like 'os/etc/switch_conf_195.220.107.207' to ring a bell for you. Where does that come from?

Hmm. Seems like that would correlate nicely with the problems that you're seeing above (specifically service checks being mangled). This last might be better for nagios-devel but I'll bet that the max size and the warning above are there for a reason. 4K is a _lot_ for plugin return data and I'll bet there are other variables that you'll need to adjust to support that, if it's possible at all.
