Hi everyone,I've been put in charge of a SQL server recently and I'm completely new to maintaining SQL. For some reason several clients when they are doing their database processing I get network_io hangs and everything comes to a halt. I have to go in there and manually kill the SPID and everything continues where it left off.SQL SetupServer 2012 R2SQL 2014 SP1Dell 850VM running in Hyper-V50GB RAMFusionIO Card10GB Ethernet between clients and serverAll workstations are pretty muchWindows 7/8.110GB64+GB of RAMSeveral CPUsSSD and SATA hard drivesIt's very hit or miss when this occurs as well, however, it's always the same NETWORK_IO cause.I've read on the Internet about how the client keep up with what SQL is sending. Could this be poor programming or do I need to investigate my network setup?
