> Key: GUACAMOLE-1703
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1703
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole, guacamole-auth-jdbc-mysql
> Affects Versions: 1.3.0
> Reporter: Ahmed Taleb
> Priority: Critical
>
> We have been getting some intermittent disconnections while RDP'ing into any
> machine setup in guacamole. I believe I've tracked the issue in the logs to
> point to 2 potential issues that may be causing the problem:
> # websocket tunnel fail
> {noformat}
> [http-apr-8080-exec-8] ERROR o.a.g.w.GuacamoleWebSocketTunnelEndpoint -
> Creation of WebSocket tunnel to guacd failed: Requested tunnel destination
> does not exist.{noformat}
> 2. Database connection issue
> {noformat}
> [pool-1-thread-1] WARN o.a.i.d.pooled.PooledDataSource - Execution of ping
> query 'SELECT 1' failed: (conn=109971414) unexpected end of stream, read 0
> bytes from 4 (socket was closed by server) {noformat}
>
> I am not really finding any information that confirms this is the reason we
> experiencing these intermittent disconnections and hoping I could get some
> support/advice.
