MPS Getting Timestamp Errors One Hour Prior to Time Change Back to CST

2016-11-07 15:23:03 Etc/GMT

•MPS Laptops were experiencing errors beginning at 01:00 (before setting clocks back to Central Standard Time). “TIMESTAMP OF COMMAND FROM CLIENT LATER THAN CURRENT SERVER TIME”

•I logged in from home and got the same error on a test MPS workstation.
I checked that the time/date and time zone on:
- My test workstation
- wpssvpcadcomm (comm server)
- wpssvpcaddb1 (Current primary DB server)
- (AD file server)
All times were correct and set for Central Time and to adjust for Daylight Savings Time.
Ran a time comparison on all CAD workstations and servers and they were with a few milliseconds of each other.
By this time it was 01:45 so I suggested that we wait until 02:00 (back to 1:00) to see if the problem resolved itself. It did. All the errors ceased after 02:00.

Have any other agencies reported this? What can we do to prevent it from happening again?

Yes In Boston we experienced the same issue during the last hour of Eastern daylight time.MPS error “TIMESTAMP OF COMMAND FROM CLIENT LATER THAN CURRENT SERVER TIME”

When the clocks switched to Eastern Standard Time the problem fixed itself. By the time I was notified everything was working fine. We are still looking into it and don’t have any answers yet

Can one (or both) of you post the MPS and MDT logs from that time period? I don't have a theory yet on why this would happen, but maybe there is a clue in the logs.

Thanks. We've taken a look at some logs and I think there will end up being a code change on the server side.

Hexagon told us that restarting the MDTSVR, MDTADMIN, RPTGEN, UEDELTA, and MDTSVR_UEDELTA services would be a workaround for this.

I set up a scheduled task to restart the services below at 01:04, prior to the time change using the ISMRequest application. It ran as planned, evidenced by the logs.

The MPS users experienced problems one hour before the time change and were still having problems after the services were restarted and they restarted MPS.

I was called out and restarted the services manually at 1:45 AM, prior to the time change. This also did not resolve the problem as it was indicated it would.

The issue stopped at 02:00 (01:00) when the time changed.

Did anyone else have this issue again and find it was not resolved by restarting the services above?

Thanks,

Brett

What version are they running? If it is 9.3 MR4, there is an I/MDT patch for that: 1-1MGH211. (It was also fixed on 9.4 Q2, 2018 under 1-TQA96N). I don't immediately see patches for other baselines.

9.2 MR5

We will be upgraded to 9.4 Q3 by next November, though. I was just wondering if anyone else was told that an I/MDT services restart would work as a workaround, and if it did.
