> Make tika-server robust against ooms/infinite loops/memory leaks
> ----------------------------------------------------------------
>
> Key: TIKA-2725
> URL: https://issues.apache.org/jira/browse/TIKA-2725
> Project: Tika
> Issue Type: Task
> Reporter: Tim Allison
> Assignee: Tim Allison
> Priority: Major
> Fix For: 1.19, 2.0.0
>
>
> Currently, tika-server is vulnerable to ooms, inifinite loops and memory
> leaks. I see two ways of making it robust:
> 1) use the ForkParser
> 2) have tika-server spawn a child process that actually runs the server, put
> a watcher thread in the child that will kill the child on oom/timeout/after x
> files. The parent process can then restart the child if it dies.
> I somewhat prefer 2) so that we don't have to doubly pass the inputstream. I
> propose 2), and I propose making it optional in Tika 1.x, but then the
> default in Tika 2.x. We could also add a status ping from parent to child in
> case the child gets caught up in stop the world gc (h/t [~bleskes]).
> Other options/recommendations?
