| Description |
|
A DB-specific write lock saw a one-time ~213 day spike in micros between a 1 minute span. (37008987922471 -> 55455750947083) First observed in MMS as a 34m spike in lock %, but ultimately traced back to serverStatus changes between consecutive MMS agent pings. Believe this has been reported by other clients on MMS side; will update ticket if I find more instances of lock % spikes. |

Hi John, Given the lack of definitive details to reproduce/investigate this issue, I'm going to close it. It's possible this is more of a reporting anomaly in MMS than a server issue; if you have any further context to add or suggestions on how to reproduce please comment. Thanks, |
