Sergei Ivanov commented on SUREFIRE-1031:
-----------------------------------------
I believe this issue is a root cause of temporary partition overfilling on our
Jenkins host.
Some of our projects contain hundreds of unit tests and they produce a lot of
output, which results in /tmp quickly filling up with files like
{{stdout9077800675661040491deferred}}.
For the time being, we had to set up a cron job to purge those files, but a
more robust implementation inside a plugin would be very welcome. Ideally, the
plugin must take responsibility for good housekeeping and remove the temporary
output files when they are no longer needed.

> Key: SUREFIRE-1031
> URL: https://jira.codehaus.org/browse/SUREFIRE-1031
> Project: Maven Surefire
> Issue Type: Bug
> Components: Maven Surefire Plugin
> Affects Versions: 2.15, 2.16
> Reporter: Vjatseslav Rosin
> Fix For: 2.17
>
>
> After the SUREFIRE-938 fix was introduced in version 2.15 there is a problem
> of two much temp files created in the temp folder. This is related to this
> issue in DeferredFileOutputStream of common-io:
> https://issues.apache.org/jira/browse/IO-397
> As a workaround it would be nice to have a configuration option for memory
> threshold size instead of hardcoded 1MB.
> Another solutions would be do delete the temp file explicitly (if it exists)
> before closing the DeferredFileOutputStream.
