Tim Allison commented on TIKA-2776:
-----------------------------------
Ugh...looks like the append=false forces the logs to overwrite, which means
that we're missing the critical points: the child log is missing between the
end of tikalogchild.log.1 (12:57) and the beginning of tikalogchild.log (13:34).
Let's change this line to "true":
{noformat}
<param name="append" value="false" />
{noformat}
>From the MCF_client_log, tika was unavailable at 13:24, 13:26, 13:29, 13:31
>and 13:34. Can you tell from the MCF logs if any files were processed between
>13:24 and 13:34? Were any files processed after 13:34?

> 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
