-------------------------------------
Hallo Tim.
I am not so expert on logging.. be patient please :-)
I configures log4j.xml and log4j_child.xml as in the attachment
I started:
java -jar /opt/tika/tika-server-1.19.1.jar -Dlog4j.configuration=file:log4j.xml
-JDlog4j.configuration=file:log4j_child.xml
but I obtain:
administrator@sengvivv02:/opt/tika$ java -jar /opt/tika/tika-server-1.19.1.jar
-Dlog4j.configuration=file:log4j.xml -JDlog4j.configuration=file:log4j_child.xml

> 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
