system execute.vi: error code 2

[54577533trh]

iv'e got some problems with my vi. 2 days ago i've enlarged my vi. and after these modifications. my vi returns an error, when it reaches the system execute vi, that calls an other exe-file.

as error code appears this message:
error 2 at system execute

possible reasons: labview memory full or¨
ni-488 no listeners during writing.

what does this mean? this error occours not every time but about in 70% of all cases.
thanks for your help

There are a lot of possiblities for running out of memory. Check for references opened but not closed, ineffecient array operations, overuse of local and global variables, attribute nodes in subVIs. You might want to try turning on the Performance Profiler to see if you can isolate where all of the memory is being used. The application note "LabVIEW Performance and Memory Management" is a good place to start for general information.
