What sort of problems are you seeing with JSON? It works fine for me.
Hal, Since I last wrote I spent a lot of time getting familiar with
ntpd configuration and I was successful getting it to lock well using
gpsd ng (refclock 46) and the "atomic" pps (refclock 22). However in
this configuration we are seeing ntpd lock up about once a day, stuck
on a mutex lock. The problem is correlated with use of the gpsd ng
refclock. Have you ever encountered this sort of problem and/or do you
have any strategies for tracking it down? There appear to be many many
places in the ntpd codebase where mutex locks are used.
I should point out that at this point, both gpsd and ntpd have local
modifications. It might make sense for me to back out my PPS mods to
gpsd, for example, to see if that makes any difference. The ntpd mods
so far should be just steps necessary for porting
