| Doc Text: |
Cause:
The previous Net-SNMP update contained a fix to improve checking of invalid incoming SNMP messages. This fix introduced a regression and some valid SNMP messages with multiple variables inside might be marked as invalid.
Consequence:
Net-SNMP tools and servers might reject valid SNMP messages and wait for "proper" response until timeout.
Fix:
Valid SNMP messages are not rejected.
Result:
The servers and utilities accept first incoming message and do not wait for a timeout.

Thanks for the report! I've fixed it upstream in commit e41c2f574c25d8dd273f2406eeeac19bc2ae16db. Hi, I have done the same test (snmp query) with net-snmp.x86_64 1:5.5-44.el6_4.4 and I get the same result: time out.
