I once had the same problem (DVB-C in my case). After some debugging I
could not find a root cause but a workaround for it:
i changed every occurrence of
eitScanStartTime = eitScanStartTime.addYears(1);
eitScanStartTime = eitScanStartTime.addDays(1);
I also did some hacks that only one transponder gets scanned for EIT as
our provider sends the EIT for all channels on one transponder.
After that, the lockup never occurred again.
The above is only a workaround and not a fix at all but hopefully might
lead some else in the right direction.
