BL lookups, they are all in the spamassasin state. I certainly hope not 
that each worker can shoot away as many as it likes. I limit it to 10 for 
a reason :) And, it always worked that way also. So somehow sometimes its 
ignored. Seen that more then once lately. Only a MailScanner restart seems 
to fix it after the strange status.

I only confirm someone else also saw, so it happenes elswhere also :)
