I tried delegating 100SP and it changed nothing, so I think no, that will sadly not help...

I am new and have 46 SP (27 in parenthesis - used to be 25 - not sure how it increased). I've been having the issue on and off for about 24 hours. If this is the problem, someone with less than 10 SP would have it worse, I guess.

Yeah the less SP you have the easier it is to hit the limit. Hopefully the other witnesses react quickly.

That makes sense. Thank you for the answer :)
