This bug has been around since about 2005, people come on forums and report that their client, which was working perfectly for months, all of a sudden only returns this error. They can't upload, download or report work anymore.

Most of the times we try to help in forums, but since none of us knows what is causing it, eventually the person is left behind without help. As far as I know, the only real fix is to reformat, reinstall the OS and reinstall BOINC clean. Which isn't good enough, imho.

So I am inputting it into Trac, as a blocker.

It would be nice to have a final answer to this problem.

The best way to figure out what's going on is capturing the network traffic (eg. with Wireshark), to see exactly what data the client is receiving. And/or running boinc under a debugger on a machine that gets such errors.

At this moment Tom is checking the maximum packet size he can send on the network (MTU). Perhaps that he's stuck behind a black hole router, or his ISP changed the maximum size of packets to be sent (without warning its clients).

Fixed. With thanks to David.
