Over the weekend, the kafka* servers saw a sharp increase in tracked connections (T131028)., which has now settled down to normal levels. We should have a monitoring metric (Diamond collector?) which reads the current table usage from /proc/sys/net/netfilter/nf_conntrack_count, so that we can track down and correlate changes.
