Plan rule failure

I have a plan rule which gives the following error on execution:

runtime.internal_error.queue_closed - queue is queue is closed.

The plan rule is supposed to receive about 8000 rows of data as input. However, it receives only 1000 rows (I passed the integration input from plan rule to a text file).

Can you please help identify root cause of failure?

Thank you.

Hello Amey,
One of the possible reasons for encountering such an error could be due to the JDBC reader step and the temporary directory it uses as a buffer for the input data. The directory probably does not have enough space. That could explain why only 1000 rows were received. Please, check this post, containing a description of how to resolve the issue.
Please, let me know if it helped you resolve the error or you still encounter issues.
