Quantum Forum for DXi V5000

We are running a DXi V1000 (2.3.2 55464-Build12).

Quite often (that is: every 3 to 5 minutes) the process "/usr/local/sbin/qtm_snmp_subagent" crashes.

That renders the SNMPD daemon unusable.

Is everyone else having that particular problem?

I was helping myself by implementing a check script which runs once a minute and restarts "snmptrapd" and "snmpd" if there is no correct answer for a snmpget.

But this certainly cannot be the solution.

@Quantum: is this behaviour known or what can be done to have this fixed?

Thanks for your help.

Hello Steve,

Are snmpd core files being generated? If so we would need to get a copy of a fresh System Diag File and a copy of the core file in order to investigate.

What firmware version is the DXI V1000?

Hi Jerry,

thanks very much for your reply.

Firmware is DXi V1000 2.3.2 55464-Build12

Yes, there are core files generated. But is it wise to upload the ZIP here for public access? Are there any other possibilities to supply the diag archive besides uploading here?

Thanks again,


Well the core files would most likely need to be reviewed by our engineering team to determine why they are being generated and to do this a support contract would be needed. Do you have a support contract or just the standard version?

Unfortunately, we do not have a support contract and rather use/evaluate the free edition.

So I guess I'm out of luck ;-)

Thanks anyway for yor help, Jerry.

I sent you a friend request so we can private message. If I can get the System Diag file and a copy of one of the core files, I can at least run a back trace on the core file for you and check our bugzilla to see if there is already a fix.

Thank you! I just sent you a private msg.
