Confluence diagnostics: low free memory


アトラシアン コミュニティをご利用ください。


This diagnostic alert warns you when your operating system's free memory falls below a set threshold on your Confluence server, or individual Confluence node.  The threshold is calculated as a percentage. 

The following appears in the application log:

WARNING ; OS ; OS-1001 ; Low free memory ; not-detected ;  ;  ; {"freeInMegabytes":...,"totalInMegabytes":...,"minimumInMegabytes":...}

This alert is enabled by default in Confluence 6.11 or later. 


To resolve this issue you'll need to either provision more memory, or free up memory by moving non-essential applications or utilities to another server.

What will happen if I ignore this alert? 

Your site may be more susceptible to out of memory errors, which can lead to Confluence crashing when Confluence is performing memory intensive tasks.

Can I change the threshold? 

Yes, you can change the threshold of this alert using the following system property:

See Configuring System Properties for more information on setting system properties.
