How is this error message delivered?  Does it get returned to the browser whenever you make a request, or do you see it somewhere else?  Does it appear in the FoxWeb Error Log?  Also, is it really once every minute, or simply intermittent?

 

My guess is that one or more of your scripts utilize a command that releases memory variables, such as CLEAR ALL, CLEAR MEMVAR, RELEASE ALL, RELEASE LIKE *, RESTORE FROM.  For more details please refer to the Illegal Commands topic in the FoxWeb documentation.
