>                 Key: TIKA-1464
>                 URL: https://issues.apache.org/jira/browse/TIKA-1464
>             Project: Tika
>          Issue Type: Bug
>          Components: parser
>    Affects Versions: 1.6
>         Environment: Os-X 10.10, Windows 8.1 (probably all op systems)
>            Reporter: Tim Barrett
>            Priority: Blocker
>              Labels: TooManyOpenFilesInSystem

> Our big data project parses many thousands of different kinds of files 
> sequentially. Up to and including Tika 1.5 this has been trouble free and 
> Tika has been a pleasure to use. The files parsed are PDF, MSOffice and MSG 
> files in roughly equal measure.
> We switched to Tika 1.6 last week and this was a good enhancement for us as a 
> number of files (MSOffice) that previously failed to parse do now parse 
> correctly under Tika 1.6.
> However we have seen that a Too many open files in system exception is raised 
> somewhere above 10000 files having been parsed. On a windows server this 
> exception is not raised but the system eventually begins to crawl.
> Watching the system's behaviour with the apache tmp files we see that the 
> apache tika files *are* being deleted from the file system, but lsof is 
> showing all these files as remaining open by the running process using Tika. 
> It would appear that the files are being deleted but handles to these files 
> are not being cleared.
