occasional EOFException from camel (jetty)

Question

We have an application that using Apache camel to call REST API. And we got EOFExceptions from jetty occasionally.

Some more observations:

• we're not using https
• it happens very sporadically (once for per 10K ?)

Does anybody known the reason and how to resolve this problem?

Thaks.

Here's the stack trace
