Hi, I've noticed a strange problem when booting diskless with limited memory. For example, even with 5 MB of memory, occasionally some random process will segfault and die. But especially with 4 megs. However, when booting diskful 4 megs is enough. I assume you need X amount of memory for NFS, but then what is X? Also, a "ps" listing shows bogus time values and every process is listed in parentheses (meaning? the man page doesn't say). For example: USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 150 0.0 1.1 460 28 v2 RV - 0:00.00 (csh) root 1 0.0 6.0 364 184 ?? Is - 0:00.00 (init) root 2 0.0 0.6 0 12 ?? DL - 0:00.00 (pagedaemon) root 3 0.0 0.6 0 12 ?? DL - 0:00.00 (vmdaemon) root 4 0.0 0.6 0 12 ?? DL - 0:00.00 (update) root 57 0.0 10.3 184 324 ?? Ss - 0:00.00 (syslogd) daemon 67 0.0 7.6 176 236 ??
