Hello Folks

Are there any plans to fix this bug?

https://issues.apache.org/jira/browse/ZOOKEEPER-1998

We are hitting a unusual problem with applications getting stuck in the linux kernel when they call getaddrinfo

This is due to a bug in linux kernel:

http://www.spinics.net/lists/netdev/msg328772.html

We hit this problem frequently as we have a number of our applications using the zookeeper client library and due to ZOOKEEPER-1998, our likelihood of hitting this problem increases. We have had mixed luck with getting a fix for the linux kernel bug, it would be good to reduce the probability at least.

Thanks,
Pramod

The linked improvement would certainly be welcome.

We ran into the same problem in a different context, and found
that upgrading from kernel 4.0.4 to 4.0.9 dramatically
improved our situation.

Maybe a similar upgrade helps you out too.
