It shouldn't die. Maybe your client kills the connection?

I tested this by making the stat() call always fail with EIO:

x select inbox
x NO Internal error occurred. Refer to server log for more information. [2007-10-06 04:24:48]
x status foo (messages)
x NO Internal error occurred. Refer to server log for more information. [2007-10-06 04:24:58]

Or even if the mailbox is successfully opened and after that:

x noop
* NO Internal error occurred. Refer to server log for more information. [2007-10-06 04:27:31]
x OK NOOP completed.
