Actually the size should be 256kb. The corresponding code is in
nxagent and looks like this:
/*
* The state machine is able to work in two phases. In the first
* phase we get the size of property data, in the second we get
* the actual data. We save a round-trip by requesting a prede-
* termined amount of data in a single GetProperty and by discar-
* ding the remaining part. This is not the optimal solution (we
* could get the remaining part if it doesn't fit in a single
* reply) but, at least with text, it should work in most situa-
* tions.
*/
lastClientStage = SelectionStageQueryData;
lastClientPropertySize = 262144;
(dont let the "last" confuse you here). So I guess increasing that
value would help in your situation. However, it looks like a bug,
since the code should loop and work wiht more than 256kb. But for some
reason not yet understood it does not...

Could be. nx contains an own mechanism similar to INCR and I have not
seen any reference to INCR within the code. So maybe it should learn
about INCR and extend its own mechanism.
Thanks for reporting that problem!
