What is your crawling queue size? I suspect one of instability reason is too big (e.g. hundreds of thousands) crawling queue size (see http://bugs.yacy.net/view.php?id=107 [^] ).

I cannot reproduce this exception at SearchEvent.java because that class has changed in between. I guess that problem is fixed. If it appears again please re-open the issue with a fresh thread dump.
