OK, I think I figured out what was wrong in my setup. Appears that
during the upgrade course I totally missed Garbage Collector settings
in jvm11-server.options. After installation from RPM it defines the
default CMS garbage collector, which is totally wrong for my hi-load
environment. I returned b

Can you get a thread dump (jstack ) when the system freezes? This
might be helpful to determine the cause of the freeze.
Also, can you reproduce this in a simpler environment (ccm + dsbulk)?
Okay, that ruled it out. Anything interesting in the GC logs? Was
Cassandra stuck at a GC safepoint? You may need to enable the detailed
GC logs to see these.

Do you have any network based mountpoint, such as NFS or samba? I have
seen similar behaviour on other Java based applications at GC safepoint
when the network based filesystem loses their connection and reconnects.

Hello!
I recently migrated Cassandra from 3.11.x to 4.0 and got strange
freezes on heavy load. It looks like some nodes in DC stopped
responding and got DN status.
I cannot check status directly on node via nodetool status or even
restart Cassandra with `systemctl restart cassandra` command. Only
