October 21, 201213 yr Hey fellow Unraiders. I recently upgraded my Unraid from RC5 8a to 5.0-rc6-r8168-test and Im having a bit of an issue. Whenever I start a large file transfer in windows using either Windows Copy or Terracopy, part way through unriad unmounts all of my drive shares. I can still access the web gui and everthing looks ok but when I look at my syslog I get a ton of "Transport endpoint is not connected" messages. I have 11WD 2TB data disks all around 90+ percent full. When I do small transfers usually under 20GB it will complete. I have attached my syslog containing the error at the bottom. I have tried to stop the array and bring it back up but the shares wont reconnect. If I restart the server everything works fine until I start another transfer. Could someone give a bit of insight. I'm not very fluent with Linux issues and when I searched the forums the only issues I could find were for pre 4.7 versions of unraid . Unraid_Syslog_10-15-2012.txt
October 21, 201213 yr 5.0-rc8a is the latest. 5.0-rc6-r8168-test is a downgrade. Did this problem occur with 5.0-rc8a?
October 21, 201213 yr Are any of the files you are attempting to transfer larger then the available free space on any single drive? It is important to note that unRAID does NOT split large files across multiple drives. Any file must fit in the space available on some single drive in the array or the transfer will fail.
October 21, 201213 yr Author Right now I'm testing the issues with a group of 1.5GB tv show episodes. In total I'm transferring 246GB. Each of my drives has between 60 and 133GB free. The share I'm transferring the files to is my media share. It's allocation method is high water. The min. Free space is set at 50GB. Split level is blank. Included disk All. Excluded disk is NONE.
October 21, 201213 yr Author 5.0-rc8a is the latest. 5.0-rc6-r8168-test is a downgrade. Did this problem occur with 5.0-rc8a? Yea sorry I switched them. I'm on RC8A
October 22, 201213 yr Right now I'm testing the issues with a group of 1.5GB tv show episodes. In total I'm transferring 246GB. Each of my drives has between 60 and 133GB free. The share I'm transferring the files to is my media share. It's allocation method is high water. The min. Free space is set at 50GB. Split level is blank. Included disk All. Excluded disk is NONE. I noticed that you stated that your split level is blank. I looked up split level setting setting in the unofficial wiki and did not find what is assumed by a blank split level. See this link: http://lime-technology.com/wiki/index.php/Un-Official_UnRAID_Manual#Split_level You may want to try a split level of 999 if you don't care about keeping specific groups of files together on the same disk.
October 22, 201213 yr Author Well I'm not at home right now, but I can go check that. I haven't had any problems like this so far with unRaid. I have been thinking of going back to a previous version to see if that changes the Transport error. When I get home I will set my split level to 999. I don't care what drive the files go on, so leaving the split level blank seemed to make that work. Thanks for the idea. I let you know.
October 25, 201213 yr Author So I changed my split level to 999 like you suggested and tried another large file transfer. I received the same error again. I downgraded my server back to RC3 and the problem went away. Still don't know what was the cause of the issue though. I also don't know if I should mark this issue as SOLVED when it may be a bug. Advice?
October 25, 201213 yr Transport endpoint is not connected happens when the SMBDaemon gets killed... How much memory do you have in the system ?
October 25, 201213 yr Author How much memory do you have in the system ? I have 4GB of ram. The only plugin that I'm actively running is simple features. That should be enough ram for that right?
October 25, 201213 yr How much memory do you have in the system ? I have 4GB of ram. The only plugin that I'm actively running is simple features. That should be enough ram for that right? Under simple features, how much ram is being reported?

Under simple features, how much ram is being reported? Simple features is reporting a total of 4GB as well. 2x 2GB sticks of single bit ECC ram. PS: I do have simple features "folder caching" option on. Maybe thhats chewing up my ram. It may also be from the fact that all of my drives are extremely full. I have a new 2TB that I am pre-clearing now. Once that's in I will migrate some of the data off my other drives to get them below 98% full. I know that being that full hinders unraids performance.
October 26, 201213 yr Folder caching does take memory... Try asnd think about the folders you cache, are there big ones you can exclude ? Example : the itunes folders are notoriously huge.. Exclude them.. Afraid of all your drives spinning up while browsing itunes ? Then limit the itunes share to one disk... Same effect. Just an example ofcourse.
October 26, 201213 yr Author When I originally had the issue on RC8a I removed simple features and all of my plugins. I continued to have the transport endpoint error. Since then I have gone to RC3. I have not had the same problem on RC3. So tomorrow I will mark this topic as solved. When 5 final comes out I will restart this topic as a bug if I have it again then. Thanks for all the help!! I really appreciate it.
