We are struggling with issues related to Mercury and IMAP connections. For a long time have observed that Mercury appears to have problems with more than 1 simultaneous connections to the IMAP server. Today I observe behavior that somewhat explains what is going on. This time it happens to me, however looking back explains what I have seen with other users many times. At one point earlier in the day I had connections with a Windows PC and at the same time with an Android tablet. I see the familiar 'Folder in user by other connections' message from Thunderbird on the PC. Next I power the Android tablet all the way off. After a long time (hours) still see the same error even though I am sure I have the only IMAP client connecting to Mercury. For the sake of test, I disconnect my connection to the Internet at this end such that my IP address no longer exists and no connection is possible for over 15 minutes. FWIW the TCPIP timeout in Mercury is set at 120 sec, I tried decreasing it to 60 seconds for test, still the same. Now, at least 2 hours after powering the Android tablet off and in the mean time totally disconnecting this end from the Internet (I am remote from the server), the Current connections window in Mercury still shows the connection. Looks very much like Mercury is not capable of dealing with dropped connections correctly.
At this point help is desperately needed. David, Peter, anyone suggestions please!
