SA memory allocation problem

[underdog]

Hi.

I have a big Labview program (~180 sub.Vi's). It is automating RF tests using 4 kinds of equipments.

At the last time I faced few strange & non-logical problems that jam the program sometimes with no Error.

Some changes I made solve few of the problems.

Now I have following error:

On Agilent ESA series Spectrum Analyzer in Initialize.vi - 1073807300 "Insufficient system resources to perform necessary memory allocations".

Another error I received:

On Agilent ESG series Signal Generator in Close.vi - 1073807346 "The given session or object reference is invalid".

I attached the relevant pictures to this message.

I'll be very thankful for your advice.

Hi underdog:

Where did you get these instrument drivers?  Are they IVI or plug and play?  What is the instrument you are communicating with that is causing this error.  Are you able to communicate despite these errors with either of these instruments?
