Priorized Queues got an error => how to process this error?

Hello together,

i configured an priorized queue for several IDOCs. Suddenly i got an error in one queue and the queue was stopped (JCO error). The IDOCs behind the error idoc stopped also because it was an EOIO queue. after deletion of the LUW the other idocs went into the receiver system. I lost the error idoc?

How can i resolve this problem without loosing any messages / data? Is there a JOB which restart priorized queues?

what does the JCO error mean? what could be the problem that this error comes up?

many thanks

Hi Alexander,

You have other option for these queue entries like Unlock the queue and refresh the queues in smq1/smq2, Execute LUW/LUWS one at a time/multi processing sometimes it works and sometimes doesnt.

JCO error is generally seen when the server is starting and ABAP instance is up and java instance of server is taking time to start up.
