      Description

      Log rotation partly failed with error: "Unable to create directory ..."

      I am using the following configuration (simplified for the purpose of this ticket):

      As part of last nights log-rotation, sub-folders "/2014/06/" had to be created on top of the already existing "/var/backups/app1/" folder structure.
      During this log-rotation task, 2 out of ~20 files (all constantly written by the same application) where not rotated in the desired folder "/var/backups/app1/2014/06/" but are still actively used in the base folder. The only hint I could find regarding this issue was the following log output from log4j (matching the rotation time):

      2014-06-24 00:00:00,084 ERROR Unable to create directory /var/backups/app1/2014/06
      2014-06-24 00:00:00,084 ERROR Unable to create directory /var/backups/app1/2014/06

      Strangely all other log-file where correctly rotated to the identical destination directory.
      Until now i was not able to reproduce this behavior in my testing environment but i suspect that there might be an issue with handling multiple log-rotations in parallel for a "to be created" sub-directory.
