ESXI connection drops while transferring file

[sleach0]

Hello,

   I am having an issue with ESXI 6.5 U3 dropping off of the network during a file transfer. The board I am using has a 4 integrated ports controlled by two Intel 82754L controllers.  I have no VMs setup as i am trying to upload the ISO files.

I created a datastore on the raid 1 drive.  I can transfer files up to about 5mb just fine but if I try to go above that the ESXI will drop off the network.  I created another datastore on one of the 3tb drives and i can transfer a file 50mb but larger that that drops ESXI off the network.  Usually ESXI is still responsive through IPMI but sometime it freezes as well.  A restart fixes the problem until i try to upload a "large" file again.

This happens on both the web client and using SFTP.

I have tried several of the network ports on the motherboard with the same result.

Hardware:

     Version: ESXI 6.5 U3 on Sandisk USB

     Motherboard: Supermicro X8SIE-LN4F

     Processor: Xeon x3460

     LSI 9260-4i with two 2.5 500gb 5200PRM drives in raid 1

     2 x Seagate 3tb drives on MB SATA controller

I found a couple of other threads but they were either hitting a 4GB limit in IE or upgraded to version 4.4 and it fixed the issue.

Thoughts?

Thanks,

Bob

hello there!

Did you ever find a solution? I'm experiencing the same thing... With my issue I just have to unplug the network cable and then plug it back in again.

Tried alternative switches and cables

Logs really show nothing.

I've just updated (VMware ESXi 6.7.0 build-19898906) so will see if that sorts it out...

Super strange.

Hi,

I am having the same issue my server.

Been running some continuous pings to my server while starting the file transfers and it seems that at different times more or less of the file is able to be transferred before the connection drops. Then I get no response from the pings for about 20-30 seconds and then the connection establishes again.

Tried with updating my drivers for the NIC but this was no success, currently running esxi version 6.7.0 Update 3 (Build 15160138)

Did update help with the issue?

Were you able to find out what caused the issue?
