kafka version = 1.0.0 kafka_exporter version = 1.4.2 prometheus period = 60s

Sometimes the server is busy is couldn't get to kafka broker,generate following error messages.

E0302 07:31:11.232962 1 kafka_exporter.go:417] Cannot get current offset of topic __consumer_offsets partition 1: dial tcp 192.168.0.1:9092: i/o timeout

kafka is normal at this point the error persists.Prometheus periodic request results in too many files open.

whenever I restart kafka_exporter, it works well again.
