I'm doing a fairly large import of a delivery unit from development to staging environment and noticed that during my content import via delivery unit that many transactions are blocked for SLT trying to perform INSERTS and UPDATES into M tables like MARA, MARC etc. I noticed that the lock is being caused by a transaction running under _SYS_REPO so I assume it's my imported views activating. Should this activation be preventing inserts and updates? If that's the case should I stop SLT mass transfer jobs prior to activating lots of views? I was thinking that my activation is only READING and should not prevent inserts/updates.
