Msg suddenly disappears

[mikeh]

I'm really confused on to what's happening here...
I have a large array of 22,000++ records.
Then I used split with fixed length of 3000 to split it to 7 messages.
I used this trick to make the 7 loops run simultaneously.

But as you can see in the image above, the flow suddenly breaks after more than 400++ loops. It's random, sometimes it breaks around 600++. But usually above 400++ loops.

What am I doing wrong here?

Does the link node at the right join to the one below it on the left?

@Colin Yes it does.. and like what I said, it runs without problem and just crashes after a certain number of loops. Around 400++ maybe.

Add debug nodes and work out which node is causing the problem. If necessary configure then to output to the log so you can analyse it later if necessary.
