There's a fairly obvious parameter in vmparam.h to control maximum process size; are there any ill effects to changing it? For example, would all other processes get huge page tables as a result, with consequent impact on system performance? Is there a limit to how high this value can be set? I'm not concerned about runaway processes; I'm perfectly willing to stick a setrlimit call into login.c to keep the soft limit at 6M or so. Please reply by mail. --Steve Bellovin {ihnp4,ucbvax,most of BTL}!ulysses!smb ulysses!smb@berkeley.arpa smb.ulysses@btl.csnet
