Using clusterssh I ran into a "256 connections max" limit of the
XWindow server. The error message was

	Maximum number of clients reached
	xterm: Xt error: Can't open display: :4

First suspect was a bad ulimit, but nofiles is set to 4096 for root and
to 1048576 for me.

Apparently there is a MAXCLIENTS constant in the sources of xorg, set to
256. Would you mind to increase it to 512 or higher for Bookworm, if
possible? 256 is easy to exceed in the era of 8K displays.

Or did I miss a configurable option here?


Thank you very much in advance
