Welcome to the all-new iMore Forums! - We're still moving some things around, so you may see a few quirks here and there, but we're working on getting things fully completed as soon as possible. For now, take a look around, and if you run into any major issues, please let us know in this thread!
Haven't heard of that, sorry. Maybe related to this, which ties in to Safari Download Manager and YourTube? Do you use either of those?
At this point, though, knowing what everything does is secondary...for now just focus on going through them one by one--turn it off, see if it helps; if not, turn it back on and go to the next one, repeat--until you find the one causing the issue. Then you'll be able to figure out what to uninstall.
One other thing that might make it easier: if you can, give us some screenshots of your Cydia packages list; we might be able to pinpoint an app or tweak with a known issue for you.
Here you go. I honestly have no clue what some of these do or why they are even there in the first place...
