If in a CIB format step of a job the output format "FormatPrinter" is used and a printer is specified which opens a dialog mask, the socket servers are blocked. If all socket servers are busy in this way, the CIB d0cumentserver cannot process any further jobs.

For this reason it is important to ensure that the printer specified via the CIB format property "PrinterName" does not open a dialog box. If the property "PrinterName" is not set and the output format "FormatPrinter" is selected, this fact must also be taken into account for the default printer.

Your CIB merge document project contains an infinite loop.

Reduce your building blocks to identify the problematic loop. Use the CIB merge parameters --maxSingleSize or/and --maxOutputSize to limit the file size and get a defined error.

You can also use the CIB merge parameter --max-executiontime, or the CIB documentServer configuration setting de.cib.docserv.job.MaxJobExecutionTime. For this you need CIB socketserver 1.6.1, CIB job 1.6.2 and CIB merge 3.10.3 or newer.
