snmpd + dataeng restart problems

Hi list,

we experience some problems during restarts of dataeng (omsa 6.5.0) and
snmpd (net-snmp v5.5-1) (on a sles11 sp1, r510)

If the snmpd server is started before dataeng is running the linux oids
won't be polled. A 'Timeout: No Response from localhost' occures

this is realy anoying - especially the dell <=> net-snmpd daemons are
not quite stable. It occures really often that the snmpwalk to the ids
won't work.

On restart of dataeng the snmpd segfaults

--------------------------------
write(3, "accepted smux peer: oid SNMPv2-S"..., 111) = 111
setsockopt(8, SOL_SOCKET, SO_RCVTIMEO,
"\5\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", 16) = 0
sendto(8, "C\4\0\0\0\177", 6, 0, NULL, 0) = 6
select(9, [4 6 7 8], [], [], {2, 768416}) = 1 (in [8], left {2, 768412})
recvfrom(8, "b\202\0\23\6\v+\6\1\4\1\205\"\325\f\1d\2\1\177\2\1\2",
1500, MSG_PEEK, NULL, NULL) = 23

sendto(8, "C\4\0\0\0\177", 6, 0, NULL, 0) = 6
select(9, [4 6 7 8], [], [], {2, 768130}) = 1 (in [8], left {2, 768127})

NULL, NULL) = 26
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
-----------------------------------------------

Are there any experiences with this? Is there a way to configure the
dell snmpd as agentx slave instead of smux?

thanks in advance
Regards
Roger
