Tim Allison updated TIKA-1464:
------------------------------
Comment: was deleted
(was: On Windows 7 with Tika 1.7-SNAPSHOT, on a batch of 3k msg files that have
many attachments, the most I can get with a 4 thread process is 12 descriptors
open at a time according to the leak detector.
The Windows task manager shows no more than 300 files open at a time for the
full process.
{noformat}
12 descriptors are open

> Too many open files in system when parsing thousands of files
> -------------------------------------------------------------
>
> 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.
