What param to tweak?

Been impossible to see/upgrade/install plugins lately.

What Java memory settings your Confluence instance run with? If they the memory allocated for your JVM is not big (e.g. below 512MB for heap size and 256MB for permgen size), I would recommend increasing your heap memory (-Xmx settings by 100m or so) and your permgen size by 50m or so. See http://confluence.atlassian.com/display/DOC/Fix+Out+of+Memory+Errors+by+Increasing+Available+Memory It's also recommended to see if you have the latest version of Universal Plugin Manager and if not, upgrade it.

The error message specifically says heap, so it seems like heap space, but in general with plugin loading you see PermGen errors. make sure it's not this:

our settings: -Xms256m -Xmx512m -XX:MaxPermSize=256m ..

How does one determine optimum size for these? We don't have that many users, but a relatively large set of plugins

I normally set both -Xms1024m and -Xmx1024m. Setting minimum and maximum to the same value means the app server grabs 1GB for the heap and doesn't have to worry about resizing.

Did you recently install or upgrade a plugin (UPM in particular)? I got this behavior after updating the Universal Plugin Manager to the latest version. I restored a backup and haven't had a problem since I've been avoiding that particular plugin upgrade.
