Maybe this is caused by intermittent pod restarts?

From a cursory search, maybe this is due to DNS settings?

I deleted the OpenLDAP pod and it recycled to a node on the R720 server. This seems to have resolved the issue. The network/cpu load on the one machine must have been too high, causing intermittent errors.
