Pastebin link to your Config (I will ignore your ticket if it doesn't contain this:

What steps will reproduce the problem?
1.Wait until the ram reaches or exceeds the limit in the ram-meter section
2.Note that the limit is exceeded and the ram-meter module does not start commands to purge the ram (/lagg gc and /lagg unloadchunks)
3.The server ends up crashing when rams are saturated 6GB

What is the expected output? What do you see instead?
Understanding why the limit is exceeded without triggering commands and especially that this function works again

What version of the product are you using?
2.8.3 for CB 1.7.9-R0.2 (actually installed)
But same result with:
2.8.3 for 1.8.1
2.9.0 for CB 1.7.9-R0.2
2.9.0 for 1.8.1

Do you have an error log of what happened?
Nothing

Please provide any additional information below.
I had this problem when the 2.9.0 version installed automatically, and since I can not restore this function. Even reinstalling earlier versions of Clearlagg. Yet I deleted Clearlagg.jar and the config file without result

ram-meter running *(ram-limit = 500, used-ram = 338

ram-meter running *(ram-limit = 500, used-ram = 597

ram-meter is running commands...

ram-meter running *(ram-limit = 500, used-ram = 149

ram-meter running *(ram-limit = 500, used-ram = 225

ram-meter running *(ram-limit = 500, used-ram = 248

ram-meter running *(ram-limit = 500, used-ram = 263

ram-meter running *(ram-limit = 500, used-ram = 296

The module runs perfectly for me. If your memory limit is 6,000mb, then i highly recommend you set the ram limit to at least 200-500mb lower. Also changing the interval lower has no negative effect on performance aside from possibly running those commands twice.
