In memory file system limit cannot be more than JVM max heap size

I started a ColdFusion 11 instance using Commandbox. I wanted to alter a setting in the CFADMIN under Server Settings => Settings; namely Maximum number of POST request parameters.

I keep getting the error In memory file system limit cannot be more than JVM max heap size.

How can I quickly get rid of this error as it has nothing to do with the setting I want to modify? I uncheck Enable In-Memory File System but this changes nothing. I set Memory Limit for In-Memory Virtual File System to 1 and get the errore message In-Memory File System limit per Application must be numeric, less than In-Memory Virtual File System memory limit, and greater than or equal to 1.

To set my parameter I eventually used cfconfig set postParametersLimit=1000.

Solution

  • I assume this is a bug in Adobe ColdFusion because CommandBox doesn't set a max heap size by default! it's just whatever your OS wants to give it. Try setting an explicit max in CommandBox.

    Also, FWIW, I'm not sure if the max post size works on a J2E install of CF. It may rely on their hacked up Tomcat version so you may want to test.
