Do you have an actual backtrace to go with this, or merely the output from the address sanitizer?

Very rare story. It appears on the test machine. It is running in a circle of 20 bots to call each other.

This isn't really enough to go on. Ideally seeing an actual backtrace and console log would provide the insight we need to see what is going on.
