Started a week or so ago for me. Can't remember what all I updated at the time so I figured I'd ask here before I go removing tweaks.
Every reboot causes a springboard crash. After a respring everything is OK.
Start removing tweaks
FYI you might want to say what tweaks you have the next time you ask something like this.
BTW...Why are you rebooting often? I reboot once a month, maybe twice at most.
I don't have enough time to list them all... unfortunately.
There is a tweak that has been updating fairly often... can't remember which, but it requires a reboot each time.
