I am running Linux ns1 2.4.0-0.43.4smp #1 SMP Fri Dec 8 13:24:16 EST 2000 i686 unknown One of the componens of initscripts-5.52-1 leaks memory, 160M in 12 hours. I did take peek at the sourcecode found missing calls to memory free function. There is no easy way to turn minilogd off short of renaming/removing /sbin/minilogd file
Something went horribly horribly wrong and syslogd didn't start correctly on your machine. It's technically not leaking; it's just storing all the system log messages until syslogd starts.
initscripts-5.60-1 will have an upper bound on how much memory minilogd will use, even though it's not technically a bug.
