LTM Logging not working correctly.

We are seeing issues with the logging of our F5 (VIPRION Based). We are running 11.5.1 and I've implemented the work around based on article K16015 (BIG IP system may be truncating log files). The logs are set to roll daily, but only holds about 2 hrs worth of logging. My question... If I want to keep about 5 days worth of logs, is this possible w/o having to push out a later version of the OS/Hotfix? I've modified the default to only write out 4 ltm logs, but the ltm.*.gz logs get overwritten daily. Do I also need to modify the maxage db variable to make sure the logs dont get overwritten? The logs we have are pretty much useless for troubleshooting.

 

Thanks in advance for any help!
