2241.0. "nmdemandpoll delete a VMS node symbol" by ZAPATA::DALLAVO (G.Alfredo Dall'Avo NSIS-Milan Italy) Thu Apr 24 1997 17:09

	Hi,

	probably I got another bug.

	I noticed that a nmdemandpoll on a VMS node causes the corresponding
	symbol/object to be deleted from the PNV databases.
	A subsequent ping forces PNV to recreate it.

	The configuration is:

		PNV server

			DUNIX V4.0b
			PNV V4.1b

		OVMS system

		AlphaServer 8400 Model EV56/440 running OpenVMS V6.2
		DEC TCP/IP Services for OpenVMS AXP Version V3.3 - ECO Level 6

	but every OpenVMS V6.2 got the same problem.

	I think it could be an UCX bug.

	In the next reply you have the log.

	I'll IPMT the case.

	Thanks in advance.

Sure looks as though you have found a bug in the target system's SNMP agent.

We can request that Tivoli consider more robust handling of agents which
return invalid SNMP information (send mail to the product manager,
Suvankar ZEKE::Ghosh), but the best choice would be to get the agent fixed.
