SNMPD segfault with CentOS5 Xen kernel

[Philipp Jäggi]

Dear mailinglist members

I like to monitor my CentOS 5 Dell 1950 Server over snmp/dsm_sa_snmp32. 
When I do now a snmpwalk, my snmpd crashed with segfault. After testing a 
while, I found out that the same problem exists with older fedora core 6 
xen kernel. With the lastest fedora xen kernel, this bug is not any more 
existant. So, I can't wait until Redhat, or CentOS will reach this kernel 
version that is actual on FC6. So does anybody have the same problem and 
hopefully, does somebody have a workarround?

Here the log entry in /var/log/messages:
