ERROR: FileRead(): SSL error on fd
I'm running conserver-8.2.4 on a 64bit Linux server, with a large
number of servers with
console sessions being managed by conserver. I've recently noticed
that every time someone logs out from a console session, the following
error is generated:

ERROR: FileRead(): SSL error on fd 4

The file descriptor changes periodically, but the rest of the error is
the same every time. Here's a snippet from the log showing the the
full order of events:

[Wed Aug 14 20:23:32 2019] conserver (5095): ERROR: FileRead(): SSL

Any ideas what is going wrong here? It doesn't seem like the errors
are causing any obvious problems.

thanks

Re: ERROR: FileRead(): SSL error on fd [ In reply to ]
I can cause the same message if I ungracefully disconnect a client. Basically, I connect and then SIGTERM the console client instead of using "^Ec.” and it produces the message.

Do you know how folks are telling the client to disconnect? Perhaps there’s some configuration option that’s triggering a similar path, but I’d need to know if there’s something more than a simple client and config going on here. :-/

That doesn’t help too much, but maybe it helps.

Re: ERROR: FileRead(): SSL error on fd [ In reply to ]
Thanks. Looks like a SIGKILL is being sent to the client in these
cases with the error.
