Do you have the steps to reproduce this problem?

Comment by markus makela [ 2021-08-20 ]

This might have been fixed in 2.5 with the some of the refactoring that was done for the RoutingWorker code, namely the removal of dcb->owner from the code.

wilsonlau78 have you had a chance to test the avrorouter with MaxScale 2.5? If you have, have you observed any crashes with it?

I'll close this as Cannot Reproduce. If you get the chance to test this and see if it still happens, I'll reopen it.
