Description
We are running ceph 13.2.5 on Centos Linux 7.5.1804.There have three monitors, three mgrs.
When do some operations on dashboard, the ceph-mgr's cpu become very high. Use 'pstack -T -p pid' and 'top -H' show that the msgr-worker-0, msgr-worker-1 and msgr-worker-2 thread take the cpu.
Use 'strace -p pid' to show that the msgr-worker-0~2 call epoll_wait very very very frequently.
Set debug_ms to 30/30 get some logs list below:

It the same as http://tracker.ceph.com/issues/38561.
Because the dead lock, the mgr's queue of ceph-mgr can't release. So it will call epoll_wait very very frequently.
