A lot of this changed between 5.7.2 and 5.7.3 to use sysctl interfaces.

With the current 5.7.3 release, and configured with 
--enable-mfd-rewrites, I think the only parts that uses kvm interfaces 
are the old and deprecated IPV6-MIB implementations inmibII/ipv6.c, now 
superseeded by the INET-XXX-MIB versions, and the hrSWRunTable that uses 
kvm_getargv and kvm_getprocs.

enterprises.5380 is not our code. According to IANA it belons to a 
company called CDOT.

Could you attach a debugger to the agent when it is hung like this and 
give us a traceback?
