I think it could help in your case, if u increase % options MAXDSIZ=(1024UL*1024*1024) % options MAXSSIZ=(128UL*1024*1024) % options DFLDSIZ=(1024UL*1024*1024) apropriately. E. g. in your /sys/<arch>/conf/<kernel name> options MAXDSIZ=(2000UL*1024*1024) But I dont know, if that is a good idea... Maybe you should use nextboot(8) in case your box does not like the new kernel... :-) -Arne __________________________________ Yahoo!
