P.S. It happened again: On my machine, from what I experienced so far, memory consumption shoots over 180MB only AFTER the first successful signature / component update (after reboot) was performed. (with protocol scanning = on) Can anyone in here confirm this?
I also encountered this problem and uploaded a memory dump to the ftp (with PM to Peter Randziak). As a side note, ekrn memory consumption jumped from 102MB (just before) to over 183MB after I performed an update (!) - no other things were done on the PC before, during or after the update. Maybe that's also a hint for something?
