Title: SNMP caching bug leading to UNKNOWN services
Component: Checks & agents
Level: 1
Class: Bug fix
Version: 2.1.0i1
An SNMP related caching bug could lead to services in the state UNKNOWN.
While this has only been observed affecting interface services, it could also affect other
services in principle.
While the services reported <i>"Item not found in monitoring
data"</i>, a service discovery would report the services to be OK, and
<b>not</b> resolve the issue.
(Users that have a version prior to this werk can resolve the issue by removing the
monitoring sites folder <tt>var/check_mk/snmp_cache/HOSTNAME</tt>)
