Hi Sebastian,
I understand that, since memory used by the cBots is now isolated from the main thread, it is lo longer possible to free up RAM from this process by using this tool.
In short, Spotware made the situation even worse.
I'd love to share your confidence regarding a possible fix for this.
However, this issue has been reported since 2013 and Spotware keeps ignoring the evidence, therefore, I can only assume they will never be able to get this sorted.
