There are two different issues:

1) Issue in Tomcat-Native (1.1.24) or in APR library it uses (1.4.6)

I do not know what it actually is.
I guess it does not understand some error code from OS. It would be
nice to know what that code actually means.

2) An NPE when trying to get remote host address to write it into the
access log file. Tomcat has to ask the address on the socket.

It fails probably because the socket is already closed.

3) Looking into bugzilla, there is known issue in 7.0.29
https://issues.apache.org/bugzilla/show_bug.cgi?id=53697

Can you re-test this with 7.0.30?
There is download link in the VOTE thread on the dev mailing list.

If the problem persists, you may file an issue.
Please provide configuration and steps to reproduce it.

4). You may want to try running with Nio connector implementation
instead of APR one.
Maybe that one will behave better / differently.
