Tim Allison commented on TIKA-2776:
-----------------------------------

How often is the child crashing?  Can you tell what is causing the problems?  Is the child actually starting successfully...are you getting any files parsed?

> 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._

> How could I workaround it ?
> Thanks a lot
