"invalid stream header" errors
I've been getting the following error from time to time. It occurs somewhat randomly, but tends to happen more often during login. Once one user encounters this error at login, all other users encounter the error at login and the site becomes inaccessible. It's difficult to tell from the stack trace what the error might be. (None of the classes I wrote appear in the stack trace.)
The application runs on JBoss 4.2.3.GA and was written using JSF and Seam.
