Strange files in home directory

Today, I find two strange files in my home directory

.#:exit -> username@hostname.30014

.#q -> username@hostname.30014

They seem to be two files link to a port. And they cannot be 'cat'. And I cannot see any usage on 30014 port with netstat.

So what do these files mean? Am I attacked by some hackers?
