EOC 2.0 report preview crashes all Orion instances

cory.cousins over 6 years ago

Case#00042056. Latest and greatest version of all modules. Loading a report preview (not a fully fledged report... which never finishes anyway) for SAM metrics within EOC against 3 separate Orion environments spins for about 20-30 minutes before all connected Orion instances become unresponsive, throw out errors, and/or are missing menus. Orion instances only recoverable via reboot of main polling engines. EOC is also only recoverable following reboot. Can be reproduced every time. All info provided to support. Just a caution...

Don't have any answers, but following for info.
We have a very similar issue. 3 Regional Pollers, one EOC. We ran a report from the EOC that never came back (No Time out, not error, just spinning) and about 2 hours later, every regional poller crashed. We found that the IIS v3 Service consumed all memory and crashed the box.
We have been unable to reproduce the issue since then. Although this make us really hesitant to move to production with the v2.0 EOC. :/

Did you happen to grab diagnostics? From Cory's case, we have been able to make some drastic improvements. If you can share those, it would be highly valuable for the team to investigate.

I Did actually.
We submitted case 46943, and if diagnostic logs are linked to the Ticket on your end, There should be two sets. The original Diagnostic logs from the day of the crash, and a expanded set with Debugging turned on.

Feel free to PM me if you need any specifics.
I'd love to help as much as I can.
Thanks!
