Nagios RAM Disk Filling Up – How Do I Fix This?

Post by TeresaKPeterson »

Hi everyone,

I’m running into an issue where my Nagios RAM disk keeps filling up much faster than expected. After a few hours of normal operation, the ramdisk reaches nearly 100%, causing performance problems and occasional service check failures.

I’ve already checked for large log files and temporary files, but I’m not sure what’s actually causing the rapid growth.

Has anyone experienced this before?

What are the most common causes of ramdisk overfilling in Nagios?

Thanks in advance!
