Samsung Galaxy S5, Android 6.0.1. Stock ROM, unrooted.
This wakelock occurs often, but not always, after app updates from Google Play are installed. The phone is left on charge overnight and play store auto update is enabled, updates seem to happen overnight. On several occasions when I unplug the phone in the morning this wakelock goes nuts and burns through my battery, but I have no idea what it is or how to stop it. I have to check the battery drain in the morning and restart the phone if this wakelock hits.
I have searched for IPSECADAPTER but found nothing anywhere on XDA or elsewhere. I don't know how I have managed to find an issue that no one else has ever seen! I have only had the phone a couple of months, got it 2nd hand, gave it a factory reset and it installed a bunch of updates when I first got it.
BBS log snippet below.
NlpWakelockAdapter is another culprit that burns though my battery on occasion but that seems to be related to areas of poor signal or similar.
