Time freezes in kstars, possible GPSD issue? was created by Greg

I'm running builds of kstars and indilib from relatively fresh pulls performed in the last week. This problem may have been occurring prior to now but I'm not sure.

I've noticed that time in kstars will get stuck at some point. Log files and FITS headers seem to continue with the correct time. This morning I found that the LT indicator in kstars as well as the log windows stuck at 21:38:32 LT while it is presently ~07:30 LT. Looking at the camera tab I see the ~20 or so exposures and associated activities (focus, dither) logged at 21:38:32 LT. I had enabled GPS logging, and see the system time being set properly at the beginning of the session, but no indication of time being frozen or other indication that something broke.

This is a short snippet of the camera tab log that shows how the time gets stuck:

Investigating the GPSD tab I saw that most of the fields were gone including lat/long. Unfortunately I didn't get a screen capture. The last log entry showed that GPS fix was obtained about 11 hours prior. I clicked on the Refresh GPS button which caused the GPSD read error to start piling up. Disconnecting/reconnecting the driver fixed it and proper time was re-established. The gpsd daemon itself was stable and showed no issues during this time.
