It looks like OpenSTA uses a timeout and your responses are to slow. Add
"%D" to your apache access log format to learn about response times.
Most likely OpenSTA will tell you about timeouts too.

The messages are only infos, the system works in principle, but a lot of
client abort messages might mean, that the system is to slow.
