I have a server that is running Ubuntu Server 14.04LTS and I am currently experiencing slow network transfer speeds. This server had been running without issue now for about 2 years and suddenly I am experiencing issues. Normally transferring a single file to this server I would get 100MB/s to 115 MB/s. Currently that speed can be obtained but only for a brief period of time. About halfway through a file transfer of 4GB the speed drops to about 50MB/s then the transfer locks up and then I get an error message that says "There was a problem accessing share" and i have to cancel the file transfer.
The server and machine that the file transfer is currently running though are both connected via Cat6 Gigabit Ethernet. The server has a hardware RAID 10 storage array so drive speed and network speed isn't an issue. Like I said earlier this system has had no issues for 2 years and suddenly this came up.
