      • VMware polling and data collection works properly and sessions are correctly closed

    Description

      OpenNMS polls and collect metrics from a VMware vCenter server. This wasn't a problem using vSphere 7.0 U2 but since 7.0 U3 it seems that some idle sessions are not correctly closed and thus not cleaned up by the vCenter server. Per default the vCenter server supports only 2000 concurrent sessions, after that OpenNMS cannot poll or collect data and user cannot use the vSphere UI anymore.

      It seems that some opened connections (in the case of retries) are not correctly closed in the VMware pollers and collectors.
