A limit to reentrant instances executed using VI server and asynchronous call?

[parsec43]

I have an application that attempts to launch many reentrant preallocated clones using VI server and the start asynchronous call function. I am finding that there seems to be an upper limit on the amount of clones that can be run using this method. The first 26 seem to run, and then beyond that additional clones are spawned but they seem to just sit there not executing. I confirmed this behavior by having them all launch front panels on execution.

Is there something I am missing here?

You're using the 0x40 option improperly.   That creates a pool of clones and is intended to created only once (I've run up to 10000 clones with one reference using 0x40).  If you want one clone per reference, then just use 0x80.
