-----------------------------------------
Summary: 1.6.0 unlike 1.5: brought on an issue where temporary
files and descriptors were not being freed
Key: FILEUPLOAD-368
URL: https://issues.apache.org/jira/browse/FILEUPLOAD-368
Project: Commons FileUpload
Issue Type: Bug
Affects Versions: 1.6.0
Reporter: David Campbell
An upgrade of commons-fileupload to 1.6.0 brought on a problem on high-load
servers where uploaded files were not being deleted and the server file
descriptor utilisation kept growing. On all server instances, file resource
utilisation kept growing to the point where it was filling /tmp completely and
then the server instances needed restarting to solve, as file space is not
reclaimed even on file deletion on Unix servers when file descriptors are still
open. The same issue occurred on all our server instances.
We had a major production incident as a result.
Rolled back to 1.5. That fixed the issue, problem completely gone.
Don't know any further details of the whys at this point.
