Hi, I have a problem running jobs in command line. I try to run a job which call other jobs (total of 12 jobs). When i run it using Talend Open Studio, it works, but when i run it in command line, i'm getting this error on a random mysqlinput : ---- Exception in component tMysqlInput_11 com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. Caused by: java.net.ConnectException: Connection timed out ---- Problem is that I get this error on random MysqlInput (sometimes I get this on the first jobs, sometimes on the last, etc... ). I saw that this could be resolved by increasing "wait_timeout" and "interactive_timeout" => they're already at "28800" so it should be okay. (?) If you have any idea what could be resolve this, I would be glad to know it Thanks. (Sry for my english, I'm doing my best).
