Recover contiguous memory in sbrio 9605

Hello,

  I have lately run into a problem of insufficient memory. Basicallly the controller is ever running and i generate data and store it in .tdms file every x sec. and every shift (3 shifts in a day) i ftp the file to the host and delete the file. During accumalation of the data the ram continuosly decreases(contiguous memory also decreases as i have a lot of array manupilations and such).

 

I want to recover this contiguous memory at the end of the shift so that the next shift runs smoothly. this is observed because i saw lot of inconsistency in the data file. Is there a vi which will free up ram and defragment it?.

 

I cannot use preallocated array because i dont know before hand how many data points i need to store. the data that will be put is in variable time.

 

Thanks in advance.

Well, there may be other issues, but if the array is large, then using, for instance, Build Array to add each element each time will result in memory issues.  Even if the final array size is unknown, it is better from the memory perspective to initialize a "large enough" array first and replace elements thereafter. If the application fills the array, it can create a new array.
