Message:

Problem of concurrency in MEMC on r_write_to_cc_send_nline register.
There was a case where the MEMC created a CC_INVAL request (due to a transition
to NCC -> CC) while sending a request CC_UPDATE what caused the crash of
r_write_to_cc_send_nline register required to send the request CC_UPDATE.
