DR strange note

[Christa Noel]

my renderslave failed immediately, the note is "GOt bogus master connection".
what is "got bogus master connection"?? i didn't touch my computer at all since render button hited.

that means something connected to the DR server, but did not obey correct Corona DR protocol. Could be corona error, mixing different corona/drserver versions, or some other application using the same port

i didn't run any other application other than corona DR on renderslavePC, & only one corona (7.2). that note comes after 3rd render jobs running (3hours /job). i cant imagine if it occur when some users do long time running animation job.
it must be corona DR bug isn't it? do i have to repost this topic to bug report board or wait till the moderator move it?

maybe... is your scene larger than 2 GB?

[Christa Noel]

my scene is a small interior, it's about 250MB. but i have no any idea how to reproduce that note.

ah i just got this problem again. check the attachments.
my computer has 2 ip address or 2 LAN connection, 1 connection is for distributed rendering (only 1 node) & the other 1 is for communication to a workgroup. maybe it could generate that tipical problem. but this is a solution for my DR delayedtime problem before, check https://forum.corona-renderer.com/index.php/topic,6218.msg42384.html#msg42384. first image comes from node was sent for just 2 minutes, big different if the nodes joined to workgroup it could takes about 15-30minutes.
no one of the workgroup member use 3dsmax or corona.

edit: if i use 2 LAN, i cannot use "search LAN" to find the nodes. i have to typed it's ip address manually.
update 1: regarding 2 ip addresses case, if i stop the render, the note on the nodes response and show "closed loopback connection" only, but stucked there .. the note "ready for connection" won't show up.. unless, i have to manually close the cmd with note "starting 3dsmax DR", so that, DR is "ready for connection" again.
