Hi Michael, It seems to be the same issue over and over. What I mean it is always issue with transaction chain. Do we need so many bugs opened for it? Let’s keep it simple as possible because we are lost in this many bugs and it may lead to confusion :) I already working on patch for all unclosed and/or illegalState txChains in all OFP. I will let you know when it is ready to test it.

Adding controller and mdsal to cc. OFP has a currently-open transaction when from the failed transaction chain (i.e. between allocate and submit/cancel) when it is calling close(). This points towards missing synchronization between the callback code and the code that is using the chain. https://bugs.opendaylight.org/show_bug.cgi?id=9101 may interest you as well in this context?
