Only questions I didn't already answer are ~100 sessions 5 shares Virtual (same config as other file servers that don't experience this) 1 CPU
Something else to add is I am snapping for previous file versions but CPU spikes never seem to coincide. I tend to agree it's something with the NIC because when System is spiking the CPU it's also the process with the highest network activity. And then it's only 2-4% utilization. There's not much I can do about that other than change the NIC type of the VM, but again it's using the same virtual adapter as my other file servers. -----Original Message----- From: listsad...@lists.myitforum.com [mailto:listsad...@lists.myitforum.com] On Behalf Of Jesse Rink Sent: Monday, September 16, 2013 2:45 PM To: ntsysadm@lists.myitforum.com Subject: [NTSysADM] RE: System process 100% CPU 08r2 what version OS is the server? nothing at all running on it other than a couple folder shares? how many users are hitting the box? how often is the spiking occuring? is it a virtual or physical box? how many cpu's or vcpus? have you tried updating the NIC driver on the server? does the cpu spike settle down on its own after awhile or do you have to reboot the client(s) and/or server? Just thinking out loud... ________________________________________ From: listsad...@lists.myitforum.com [listsad...@lists.myitforum.com] on behalf of N Parr [npar...@mortonind.com] Sent: Monday, September 16, 2013 2:24 PM To: 'ntsysadm@lists.myitforum.com' Subject: [NTSysADM] System process 100% CPU 08r2 I've been troubleshooting this for months now and I'm not getting anywhere but more confused. I have one file server that keeps spiking the system service at random times. Nothing else is running on the server, no AV or other apps. When this happens my win7 clients trying to access files on that server will come to a screeching halt. That's the really strange part, my XP clients keep working like nothing is wrong. I've done all the trouble shooting I can find for this problem, it's very hard to narrow down exactly what's causing the "system" process to spike. I noticed that one of the win7 clients in particular was moving a lot of data (receiving .5 MB/sec steady) but they had no apps running off the server, weren't searching, search service was turned off. But on that client it was the "system" service that was receiving the data from that server. I rebooted the client and the server cpu immediately went back to normal. My googling can't find anything that links the two together. Just hoping someone else has encountered this. Both client and server are patched but this has been going on for a long time, at least the last couple years. Thanks
