      Description

      We got the issue as "too many files open"

      After some searching/investigation, In the end , we realized the issue came from google-storage-plugin

      repro steps are as below:

      1) Create a freestyle project

      2) add log upload as post-build action

      3) set "Max # of builds to keep" to 3

      4) rebuild the project a few times

      5) get processId with ps -ef | grep java | grep -v daemon | grep -v grep | awk '

      { print $2}

      '

      6) lsof -p $processId | grep deleted

      I can get below

      java    6480 jenkins 780r   REG                8,1     2178   19014020 /var/lib/jenkins/jobs/file-handle-leak/builds/.1/log (*deleted)

      java    6480 jenkins 780r   REG                8,1     2178   19014020 /var/lib/jenkins/jobs/file-handle-leak/builds/.2/log (*deleted)

      java    6480 jenkins 780r   REG                8,1     2178   19014020 /var/lib/jenkins/jobs/file-handle-leak/builds/.3/log (*deleted)

      BTW, for a finished job #5 but hasn't been deleted, we can get below result.

      java still hold the open file of the job log which seems to be a issue

       lsof -p 6480 | grep file-handle-leak
