Hmm. I'd really like to know why that's behaving different.
Usually there are only timers in the CLOCK_MONOTONIC base during boot. CLOCK_REALTIME base should be empty most of the time. If my theory is correct then the number of reprogram events is correct as well because base[MONOTONIC]->first is always the one which armed the timer.
Can you add some debug which tells us to which base the removed timer belongs ?
Thanks,
