Thomas Wolf commented on SSHD-1174:
-----------------------------------
Sorry, this bug report is not actionable. There is not enough information.
"Some" server? Which one? "Sometimes"? Any hints as to under what conditions?
What do the client's and preferrably also the server's debug logs show? What
kind of operation is being done?
Best would be of course if you could provide a Java test program with
instructions how to run to reproduce the problem. But if the problem occurs
only occasionally, that's perhaps not possible.
