Comment 28 for bug 584529

I don't have any experience of interpreting nspr logs, so take this with a grain of salt...

It seems that almost immediately after wakeup, TB tries to re-establish the connection but hostname lookup fails (NS_ERROR_UNKNOWN_HOST). This probably makes sense because the network is not yet up at that time.

After a while, I click "Get Mail". TB tries to open a new connection, but immediately fails again with NS_ERROR_UNKNOWN_HOST. It appears that this result is cached from the previous attempt.

I will add resolver logging too to see if that gives additional any insight.
