While in my mailbox and browsing through emails on the squirrel mail webmail site, I will randomly receive the "Unknown user or password incorrect" error page. Upon trying to log back in, it will give me the same error. I have to close all browsers, re-open a window, and log back in. It will work for a few minutes and then log me out again.
I've checked dreamhoststatus.com... nothing reported.
I'm on the homiemail-sub4 cluster.
I'm not being idle or staying logged in for hours. If that was the case, I could see why I'd be logged out for timeout or whatnot. But this is really strange.
