Sometimes tests fail because connection fails with:

Even though it says "reconnectng" it does not work after that.
Comment 1 Egor Ushakov 2010-09-28 08:47:36 UTC 
Andrew, you disabled full reconnect on "channel is not opened" when you fixed 10 processes issue, it looks like it did not help in this case. Maybe we should still do full reconnect in this case?
Comment 2 Andrew Krasny 2010-09-28 08:54:26 UTC 
No... this is bad idea. 
Full re-connect means closing all active channels (means killing all currently running remote processes)... Don't think this is a good idea...
Comment 3 Andrew Krasny 2011-03-16 12:36:41 UTC 
Egor, is it still reproducible?
Comment 4 Egor Ushakov 2011-03-16 13:39:52 UTC 
yes, I've seen see the same error on March 14
Comment 5 Leonid Lenyashin 2012-10-30 21:09:43 UTC 
There was no activity on this issue for quite a long time. We apologize that the issue was not addressed so far due to lack of development resources. We might not have time in near future to fix this problem, so it is closed as WONTFIX.
If the issue is still critical for you please do not hesitate to REOPEN it.
Thank you for using our product and reporting bugs. We are really sorry that we were not able to fix this issue timely.

Regards,
CND team.

Comment 7 davelhs03 2017-03-08 17:01:36 UTC 
Typo: Also getting this issue **with** a laggy connection.
