We are running a VT100 for CK71 scanners. But few times per week, out scanners start having massive connection issues.
When this happens:
Event viewer is flooded with:
- "The terminal with ID xxx did not receive a reply from the CSS within 69000 milliseconds."
- "There was a problem replying to internal key xxx. A reply could not be received for terminal xxx. Terminal will be resetted. Thread: xxx"
Also:
- The nassql.exe process is also pegging out the CPU. Well, just the one thread of the cpu it uses.
- You cannot stop/restart the NAS service. You have to kill the nassql.exe process
- Sometimes this fixes it right away, other times the issue comes back in a few minutes.
We are running:
- NAV 2009 (NAV 6.0) on Server 2008 R2 (64bit) with SQL 2008 R2
- NAS is on a different Windows server 2008 R2 (64bit)
I am not sure if the CSS errors are the cause of the nassql.exe process wigging out, or if the nassql.exe wigging out is causing the CSS errors.
Does anyone have an opinion of what the issue might be?
