It seems a call to process-status could be added to avoid the error.

However, Gnus/nnimap is supposed to check whether the server is alive
before attempting to use it, and that code call process-status.  So a
proper solution may be to track down what Gnus/nnimap operation it is
that call the backend unconditionally, and fix that, then the server
would be automatically re-opened as well.

I can try to find to work on adding the process-status call in
imap.el, to avoid the error, but depending on error propagation, it
may not be sufficient.  It will take a while, though, so if you or
someone want to look into this, that would be appreciated...

You might want to test with GnuTLS instead of OpenSSL too, tls.el
might be more reliable.

Thanks.
