It’s most likely that one of the WebStone clients died before it could report results to the webmaster. We’ve squashed many circumstances in which this happens, but bugs continue to appear, especially on systems we haven’t tested. We can’t do much for this kind of problem without debugging traces. Edit testbed, and set the DEBUG parameter to DEBUG=-d, so that debugging info will be written to files named /tmp/webstone-debug.. If you can replicate this problem with debugging turned on, please let us know. We’d love to examine the traces. Another possible source of problems with reading timing info is when a page in the filelist did not get read by a client, but the webmaster was expecting to find it. This can happen when the test time, number of clients and filelist distribution are set up so that a file which gets read infrequently does not get read _yet_ before the test period ends.This will get ironed out in a later release of WebStone.
