Hello again!
Bowen, your answer was right. After forcing clock synchronization, the
count of MUTATION messages radically dropped down. After sync I made
full repair on affected nodes and now I don't have any MUTATION drops
in logs. Thanks for your help!

First thing to check, do you have NTP client running on all Cassandra
servers? Are their clock in sync? If you answer "yes" to both, check the
server load, does any server have high CPU usage or disk utilization?
Any swapping activity? If not, check the GC logs, and looking for long
GC pauses.
