I take it back. There are still Tesseract processes that have been up for 4+
minutes, even with `tika-config.xml` and `X-Tika-OCRTimeout` set to 30:

I don't understand how this works.

> Key: TIKA-3103
> URL: https://issues.apache.org/jira/browse/TIKA-3103
> Project: Tika
> Issue Type: Bug
> Components: ocr
> Affects Versions: 1.24.1
> Reporter: Radim Rehurek
> Priority: Critical
>
> We're using the Tika Server with OCR:
> _java -jar /opt/tika/tika-server-1.24.1.jar -p 9998 -spawnChild -JXmx500m_
>
> Two undersirable things happen:
> h3. 1. The CPU runs at 100% for >10 minutes, long after any Tika requests
> have finished.
> These processes show in _top_ as "tesseract" (OCR) and consume all CPU cores
> at 100%.
> They eventually die (or finish?) but the machine is unusable in the mean time.
> *Expected behaviour:* Tika cleans up spawned processes after itself: at most
> after its timeout limit (which is 2 minutes I believe?)
> h3. 2. The temp is full of files like:
> {{root@38acd588ee22:/# ll /tmp/}}
> {{total 197320}}
> {{drwxrwxrwt 1 root root 24576 May 20 09:35 ./}}

> *Expected behaviour*: Tika cleans up disk space after itself.
>
> These bugs are critical for us. What's the best way to avoid them?
