What do these MTBF/MTTR error messages mean, and how do I prevent them?

[ FlexSim 16.2.1 ]

I have Operators set to periodically breakdown with an MTBF/MTTR. FlexSim is intermittently reporting the following error on the System Console when an Operator exits the breakdown state:

time: 35109.004386 exception: Exception Caught in resumeobject(treenode involved, int id)

time: 35109.004386 exception: Exception Caught in ObjectFunction202__project_exec_commandlist_resumeobject_node object: MAIN:/project/exec/commandlist/resumeobject/node class: MAIN:/project/exec/commandlist/resumeobject/node

time: 43246.708754 exception: Exception Caught in stopobject(treenode involved, int state, int id, double priority)

What do these error messages mean, and how do I prevent them from happening? When this happens, the operator in question does not appear to exit the breakdown state. The MTBF/MTTR down function is set to "Stop Object" and the up function is set to "Resume Object". I have the breakdown set to break down members individually. If I manually run a resumeobject on the operator, it works fine. I am unfortunately not able to share the model that this is happening with. Thanks for any help you can provide.

[joerg_vogel_HsH]

The Stop ID is the same for the combination of stopobject and resumeobject and if you use a pointer like item or involved object this pointer object still exists in your model when you call the function resumeobject?

[matt_long]

Can you post your model or a subset of your model showing the problem? Not sure what it could be with just the error.

Or try to replicate the issue in a small sample model rather than your confidential model, and then post that.

This issue isn't consistently happening, so I am unable to provide any additional info at this time. If the issue happens again and I am able to reliably reproduce it, I will reduce the model to something sharable and upload it here. Thanks.
