The Data hub process is getting stuck at Composition stage frequently. In the Composition action table i find a record is in IN_PROGRESS and the remaining records following that are in PENDING state. Also the publication action is not performed as it gets no data. Why the Composition process is getting stuck?

What version of DataHub are you running? Do you use custom composition or grouping handlers?

Most likely custom grouping handlers cause infinite loop of data manipulation. Also, check of exception stack traces in the log output. Not likely but it's possible that an exception interrupts a composition without updating the status of the composition action.

General recommendation, try to reduce the data set to as small as possible, which still produces the hanging effect. Then trace the log output or debug, if needed.
