Hello,

With lms3.1, from device center the first SNMP walk is OK.

When we try to do another snmp-walk either on the same device, either on another device , we recieve this error message:

On what platform is LMS installed? How much swap space do you have configured? What starting OID are you using?

mmisonne · ‎12-15-2009

Hello,

- Lms is installed on Windows 2003 SRV enterprise edition SP1

- Swap space is Min 4096 Mg and Max 8192 Mg

- This pb appears with any starting OID

Also, this problem appears with different client-PC, the first time it is OK, then the next time it gives this errors on different PC.

Customer has to wait another time ( next day) to make it work again.

What version of SNMP are you using in the SNMP Walk tool?

mmisonne · ‎12-16-2009

Hi,

It is snmp V3

I cannot reproduce. I have an LMS 3.2 server running on Windows 2003 EE, and I went to Device Center, and performed an SNMP Walk on a switch using SNMPv3 authNoPriv:

Username : v3user

Password : ********

Auth Algorithm : MD5

Starting OID : 1.3.6.1.2.1.1

I can run multiple SNMP Walks in a row with no errors. I will need more details on exactly what options your customer is using in order ot analyze this problem further.
