It's fairly easy to limit the amount of memory that VFP will use. I wrote about this is my session on misleading error messages a few years back. You can download the full paper from http://www.peisch.com/downloads.html in the file called ErrorMessages.zip. Here's the excerpt for this particular error:This error may actually be the result of too much memory! It seems to crop up on systems with 1 gig of memory or more. The way to solve this is to direct VFP on how much memory to allocate with the SYS(3050) function. Steve Dingle was having problems with this error, and has come up with a formula for setting SYS(3050). #DEFINE diMEM_MAX_FOREGRD 256 && The max memory to allocate #DEFINE diMEM_FOREGRD_PRECENT .90 && Percent of memory to allocate LOCAL liNewMemory,; liAvailableMemory m.liAvailableMemory = ( VAL( SYS(1001) ) / 4 ) / (1024^2) m.liNewMemory = INT( m.liAvailableMemory * diMEM_FOREGRD_PRECENT ) IF m.liNewMemory > diMEM_MAX_FOREGRD m.liNewMemory = diMEM_MAX_FOREGRD ENDIF m.liNewMemory = m.liNewMemory * (1024^2) =SYS(3050, 1, m.liNewMemory ) && Set foreground memory =SYS(3050, 2, m.liNewMemory ) && Set background memory This code allocates 90% of memory to foreground and background buffer memory. You may want to play around with this number. You shouldn’t need to increase the maximum above 256 megs. You also probably want to make these values configurable instead of hard coding them. The

There are several potential causes for this: Scenario #1 - Code production problem in Controller 2.3 MR1 sp5 or earlier Scenario #2 - Code production problem in Controller 2.3 MR1 sp12 or earlier Scenario #3 - Limitation in Controller 2.x, which is solved by migrating to Controller 8.x Scenario #4 - Application server may be overloaded by running too many simultaneous consolidations. Resolving the problem Workarounds: Depending on circumstances, it is possible that some/all of the following workaround
