Unanswered Question
Dec 14th, 2009


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?

-       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.

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 :

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.
