Pop-Up: Operation is not allowed when object is closed

[ea0921]

Hello,

I am having a version-controlled package in EA which is syncing from source to other project of EA.
Operations I am performing,

1. While writing any create/update, first take check out of the package
2. Perform create/update operation
3. Perform check in of the package.

While performing this I am getting pop-up of operation is not allowed when object is closed..
Also, there are many requests going on parallelly on the same project at the same time.

Why do I get this type of error in version-controlled package, and how to solve this error or how to avoid this error?

Thanks

"While performing this" is pretty broad.

It would be more helpful if you could really pinpoint what exactly you (the code) are doing when this error pops up.

Doing lots of things in parallel, especially on local database files is probably not the best idea.
I can imagine that an object that you are trying to use is already discarded (closed) when you try to use it.
But without code and the exact circumstances we can only guess.
