    Hi Community,

    today i saw in qradar deployment running 7.5.0UP8IF03 an unusual error message related to /etc/cron.hourly/logrotate command.

    I realized that the /var/log partition size reached 94% of diskspace. So i followed the ibm technote to investigate starting with 1. Troubleshooting /var/log/ space issues:

    https://www.ibm.com/support/pages/qradar-resolving-high-disk-usage-problems-varlog-partition

    And during this i tried to run the logrotate command and saw the mentioned output. Finally i solved this issue and were able free up some space.

    Any ideas or hints related to this fix this lograte error output?

    Regards,

    Ralph
