Getting connection aborted message when processing pdf files

[minump]

When uploading a pdf file, the pdf2text-extractor kicks in, after "submission for extraction", multiple "Connection aborted" messages are being logged.

The file is again submitted for extraction and the cycle repeats. This is noticed in the local instance when extracting large pdf files. Not able to check this out in consort instance because of radiant volume detaching issue.
