             Summary: Tika server child restart
                 Key: TIKA-2776
                 URL: https://issues.apache.org/jira/browse/TIKA-2776
             Project: Tika
          Issue Type: Bug
            Reporter: Mario Bisonti


Hallo.
I use tika server standalone started with the option:
java -jar /opt/tika/tika-server-1.19.1.jar -spawnChild

I use ManifoldCF and Solr to index file using tika server.
It happens that indexing is continuously crashed because I obtain many:
Tika down, retrying: Connection reset
etc.

I suspect that, when a process is restarted, the client crash as mentioned here:
_If the child process is in the process of shutting down, and it gets a new 
request it will return 503 -- Service Unavailable. If the server times out on a 
file, the client will receive an IOException from the closed socket. Note that 
all other files that are being processed will end with an IOException from a 
closed socket when the child process shuts down; e.g. if you send three files 
to tika-server concurrently, and one of them causes a catastrophic problem 
requiring the child to shut down, you won't be able to tell which file caused 
the problems. In the future, we may implement a gentler shutdown than we 
currently have._

as reported here https://wiki.apache.org/tika/TikaJAXRS

How could I workaround it ?

Thanks a lot

Mario
