CentOS 5.5; Kernel 2.6.18; OpenJDK 1.6; Jenkins 1.427
At least once a day, we are seeing Jenkins slow to an absolute crawl, where requests take ~5 minutes to load a page. CPU load is usually fine (~1 or less) and there doesn't seem to be anything on the machine. However, the logs from Jenkins are hundreds of the following, over and over again:
[Winstone 2011/08/26 14:07:52] - Error within request handler thread
java.io.EOFException

I have attached two thread dumps (about 10-15 minutes apart).
