The automation issue could be due to the fact that DET_MAIN is asked to go to SHUTTER_CLOSED in order to have ITF_LOCK reach LOCKED_RECOMBINED; looking at the log it seems that this failed with the following error:

2018-10-16-18h27m51-UTC>WARNING-[SHUTTER_CHECK_OPEN.run] USERMSG 0: No power on B1s1/Bs2 PDs, shutter probably not open

My naive guess is that something has changed after the B1s1/B5 swap.

About the crash of LSC_Acl, this is most probably the same problem already occurred in the past when, because of some weird interaction between Acl / cm / PythonVirgoTools, an Acl process crashes when something tries to access a recently modified ACL_SUM_CH or ACL_MATRIX_CH object, whose number of inputs has changed; in this case I think this was triggered by the removal on the B1p_119MHz signals from the LSC sensing matrices. I am not sure though how to cure the problem, as reloading a Metatron node is not always sufficient (but sometimes it is), as the AclServer objects in PythonVirgoTools do not completely replace themselves upon RELOAD. We could think about some "flush" directive which deletes the Python objects from the userspace before reloading a new instance...
