Available drive space is less than twice the value of physical memory. This is dangerous because it does not provide enough room for a full memory dump with continued operation



SharePoint Health Analyzer is a good feature or we call it as a revolution for SharePoint administrators as it helps you to detect the issues in your farm and keep the SharePoint up and working without any worries :)

It’s very important to take an immediate action in reference to the critical errors which are reflecting in the health analyzer.

Overview of SharePoint Health Analyzer

As per the error message, make sure that the mention drive is having enough space as per the Microsoft recommendations. If you are pretty sure that space is already there and still you are getting that error in the health analyzer then you need to follow the following theory which has been explained by MVP-PAUL STORK

This theory suggest- “the threshold is built into the code and can't be changed.  You can go into the configuration for the Health Analyzer and turn off that particular rule.  To do this go to Central Administration and navigate to Monitoring > Health Analyzer > Review Rule Definitions.  Then find the specific rule, edit it and disable it.  It will stop telling you that the disks are running out of space.  I'm also not sure that this rule only pertains to the drive where you have your log files, but the only thing you can do is disable the rule.  There is no way to edit it.”

What you can check to free up the space:
-       Check the log files which are stored on the drive – this consumes most of the space
-       Check the backup files which are present over there
-       Check the old deployment files which are present on the same drive
-       Check the software’s which has been used long way back and still using the same space
-       Check the misc stuff which we kept during any critical situations (example: any files, tools etc)

As per Microsoft MSFT- Rock Wang—“This rule checks disk space as a proportion of the RAM on the computer. When disk space is less than twice the RAM on the computer, the health rule triggers an error. When disk space is less than five times the RAM on the computer, the health rule triggers a warning. Accordingly, server computers with lots of RAM are more likely to experience a failure of this rule.”

Once you remove the unnecessary stuff or irrelevant data from the mention drive then click on “Reanalyze now” so that it will verify the error and shows the results immediately.

If you have any queries/questions regarding the above mentioned information then please let me know, Thank you…
