David Campbell updated FILEUPLOAD-368:
--------------------------------------
Description:
An upgrade of commons-fileupload from 1.5 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.
