just app. 2 months ago we had increased the allowed memory size for php/mysql (on which 2bu.biz is based) on our server and now 2bu.biz is exceeding our resources again. i will check with our technical support what we can do, but it seems that 2bu.biz requires ever increasing server resources. please also check with your web site developer whether there is maybe some script error/bug which could cause this.
