Bug #3627
TVHeadend locks up and spins a CPU after the Spring DST change
100%
Description
Last night when the time changed for Daylight Savings Time, both of the TVHeadend instances I operate became unresponsive and starting spinning one CPU core at 100%. After restarting, they resumed normal operation. I have attached full GDB backtraces from both of them.

Unfortunately, it really difficult to track what's wrong there - I need to know where it loops, some analysis:
now=1457849040, zone=EDT
TZ=/usr/share/zoneinfo/US/Eastern ./a.out "4 14 * * *" 1457849040 TIME = 1457849040 - 2016-03-13 01:04 (DST 0) (ZONE EST) min = 000010000000000000000000000000000000000000000000000000000000 hour = 000000000000001000000000 mday = 1111111111111111111111111111111 mon = 111111111111 wday = 1111111 NOW: 2016-03-13 01:04 NXT: 1457892240 - 2016-03-13 14:04 (DST 1) (ZONE EDT)
but...

ok.. ota epg has also second time...

I don't really understand what you posted. Is there something else I can do to help provide more data?

I still think this is an issue.
tvheadend was unresponsive after October DST change in Australia.
