By cache amount, do you mean the number in brackets? If that's it, and it's taking an inordinately long time to count down, that typically means a crapload of headers, often singular, spammy ones, have shown up in the group. You should indeed let it settle down first if at all possible. If it's crazy, like you've left it overnight and you've never seen this before, something might be wrong, yeah.
