Ilya Kasnacheev commented on IGNITE-11730:
------------------------------------------

[~akalashnikov] seems like this fix is working, I can no longer cause clients to segment.

> There is a check that Discovery Data Bag compression is supported by all nodes.

is at least one client node that does not support this feature, clients will still send zipped
data that server would not understand, leaving to following server error:
