You are probably running out of space on disk or the limits for your NiFi repository are being reached.

Have a look at the article below and try to reduce retention and/or increase the available repository space.

also 

1] - Add the following property from Ambari under nifi.properties section to a value of 75%
nifi.content.repository.archive.backpressure.percentage to 75%

2] Increase the disk space.
