Коллеги, вопрос
Как мне узнать, что именно - т.е. какой индекс, какие его значения взаимно блокируется транзакциями - блокировка
LCK_M_RS_U
A transaction is waiting to acquire a key-range lock on an index. This lock has two components:
a lock in shared mode on the range between two consecutive index entries or rows. The locked range can't be modified but can be read by other transactions.
a lock in update mode on the index entries or rows. The locked rows can’t be accessed by other transactions while an update is performed.
Key-range locks protect the rows included in a record set, and prevent phantom reads, insertions and deletions when the T-SQL is using serializable transaction level.
