Radim Rehurek updated TIKA-3103:
--------------------------------
Description:
We're using the Tika Server with OCR:
_java -jar /pii_tools/tika/tika-server-1.24.1.jar -p 9998 -spawnChild -JXmx500m_
This used to work fine in previous versions (1.22, without _-spawnChild_).
But after upgrading to 1.24.1 with _-spawnChild_, two undersirable things
happen:
h3. 1. The CPU runs at 100% for >10 minutes, long after any Tika requests
should have finished.
These (zombie?) processes show in _top_ as Tesseract and consume all CPU cores
at 100%.
They eventually die 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 ./}}
