snmp monitoring

I've been trying to get the snmp monitoring with cacti
going, but I've
run into a snag. After I set everything up and run an snmp
walk to test
the setup, the subagent crashes. Here is part of what I get
from strace:

gettimeofday({1169063878, 909115}, NULL) = 0
select(8, [4 6 7], NULL, NULL, {6, 52205}) = 1 (in [4], left
{6, 56000})
read(4, " ", 1)                         = 1
writev(2, [{"/opt/fedora-ds/bin/slapd/server/"...,
42}, {": ", 2},
{"symbol lookup error", 19}, {": ", 2},
{"/usr/lib/libnetsnmpagent.so.5", 29}, {":
", 2}, {"undefined symbol:
hosts_ctl", 27}, {"", 0}, {"", 0},
{"n", 1}], 10) = 124
exit_group(127)                         = ?
Process 29587 detached

I'm running fds 1.0.2 on FC4. If someone could point me in
the right
direction, I'd appreciate it.

Thanks,

Scott

I may have to try that . . . though the howto on the wiki
says it covers
only version 1.0.2 and the previous thread on this subject
states that
they are using 1.0.2 as well. Oh well, I'll have to play
around with it
some more when I get back to work.
