> Project: Kafka
> Issue Type: Bug
> Components: core, network
> Affects Versions: 0.10.1.1
> Environment: Centos 7

> Reporter: Joseph Aliase
> Labels: reliability

> Kafka is running out of open file descriptor when system network interface is
> done.
> Issue description:
> We have a Kafka Cluster of 5 node running on version 0.10.1.1. The open file
> descriptor for the account running Kafka is set to 100000.
> During an upgrade, network interface went down. Outage continued for 12 hours
> eventually all the broker crashed with java.io.IOException: Too many open
> files error.
> We repeated the test in a lower environment and observed that Open Socket
> count keeps on increasing while the NIC is down.
> We have around 13 topics with max partition size of 120 and number of replica
> fetcher thread is set to 8.
> Using an internal monitoring tool we observed that Open Socket descriptor
> for the broker pid continued to increase although NIC was down leading to
> Open File descriptor error.
