emeadaxsupport: Memory usage in XppIL code

Written some X++ which seems to have high memory usage when run in IL but runs normally when not in IL? Or just noticing high memory usage in servers running IL code?

Here we're going to talk about an aspect of garbage collection in XppIL that is important for anyone writing XppIL code to take on board.

Let's start with an example: If the code below runs in XppIL, when we hit the sleep line how many X++ objects are in memory (the query Cust contains CustTable and CustTrans):

<div style="background-color: lightgray; font-family: Courier New; font-size: 8pt; padding: 5px 5px 5px 5px;"> for(i=1;i

• Take care with use of certain kernel X++ classes in your IL code – for example TreeNode, UserConnection/Connection, Query, QueryRun and so on. You can call finalize() on these when you know they’re no longer needed to release them in your code.
• If writing a while select, and you use break; within the braces, then this will leave the table buffer open until the IL code completes. You can call buffer.clear() to manually release it. If the while select naturally completes with no break; then it’ll release the buffer on it’s own.
