[c-nsp] Strange issue

[james list]

Dear experts
I'm wondering if you can provide any hints/help on this problem.

We experienced a strange issue in reaching the remote devices (servers) and
perforiming bulk snmp walk, instead direct object query was working fine.

After an entire nigth of issues (22pm to 6am), the problem disappeared
alone...

During this problem we've experienced also others isses, but we was not
able to find the root cause nor any issues on our firewall.

We asked to the carrier (which has also firewall in the middle since it
provides services) but it seems also it didn't detect any issue.

I think the carrier had some problem but I'm not able to prove it.


Have you never seen this kind of issue ?

What can be realated to ?

Thanks in advance for any suggestion.

Cheers
James
