I think it's likely the CM failed the transition because the
connection timed out.  It may be worth increasing the local and remote
response timeouts (__srp_issue_session_login) if you're going to have
a lot of debug output.

I added a debug print (TRACE_LEVEL_WARNING, AL_DBG_CM) for these cases
to help pinpoint the reason for the failure in revision 477.

I added a sleep before the RTU call to duplicate this and it worked.
I'll investigate tomorrow.

Thanks,

- Fab
