I've sent a ticket but i couldnt send my file through your plugin, everything is described in my notification I can't wait for the results, thank you :)

Hey Is that ok if i setup FTP server on my machine for you to download files?

Well, i think that was kind of a bug in my linux distribution (was Kubuntu 17.x not LTS and now it is 18.04 and its LTS version) or smth. Only difference between the first installation and the 2nd was that i used only headless instance of render server instead of running it with GUI in running blender. I believe that was the problem, somehow i doubled(?) crowdrender servers on a machine. I couldnt unplug ILO because sometimes i have to connect to the server via JIRC, check server's status etc. Server was using static IP on both ilo and ethernet ports. There was no problem with names. When i reinstalled linux and cleared server list in blender, after connection attempt it worked just perfectly.... only with small projects but with large ones we have a problem described here in other thread ->https://www.crowd-render.com/forum-1/general-questions/why-servers-are-not-sending-back-their-render-result

Hello I will check the logs soon. The problem is not noticeable with small projects (both linked and not, using f.e. 7 servers we have up and running now) but i'd say 75%-90% of large projects (i mean like 4+ or more GB files etc) fails with sync or render. If somehow we have synced 4 servers we have noticed 3 ways to "finish" the render. 1st - after servers jobs are done, rendered image returns to host and is getting "glued" into one piece 2nd - renders are not returning (all of them, not piece or two) but they are rendered in dir /cr/server/UUID/file.exr 3rd - everything crashes including headless instances servers We have found a way to render linked projects, network usage of host ethernet card is peaking at 900Mb/s+, on slaves too due to linked files. As i saw, communication between host and slaves goes through TCP and is using jumbo frames, am i right? I have never found any info about that. Can jumbo frame and/or MTU config be the problem in our case? I’m looking forward to your opinion. Kam

Hello Thank you for your response, this problem has been fixed. I've reinstalled the Linux to the newest LTS version
