Unexpected crash when using --net=host

[eliecharra]

Hi,

I'm experiencing strange issues on some openstack instances, when starting instances with --net=host, couchbase is continuous crashing.

docker run --net=host -ti --rm --name couchbase couchbase:community-4.5.1

Hi @eliecharra, if you have the ability to open a support ticket that's your best bet.

Otherwise, I don't see anything obviously docker-specific here, so I think you're better off posting a question on the support forums, and if it's clearly a docker issue w/ an action item, we can re-open an issue here.
