Dear Ken,
Thank you for your patience.
The development team analysed the issue REVIT-113310 [Document.ReloadLatest leaks RevitServerInternalException] and say:
I could not reproduce this issue. Document.ReloadLatest works without any exception when another user's SWC is committed in the middle of the ReloadLatest. Reproducible steps and journals is necessary for us to continue the investigation.
Can you please provide a minimal reproducible case for the development team to analyse?

Please also add the journal files produced when you encounter the problem your end.
Thank you!
Cheers,
Jeremy
