Since upgrading to SAM 6.3.0/NPM 12.0.1 (we went straight from SAM 6.2.3/NPM 11.5.3 to SAM 6.2.4/NPM 12.0.1, so maybe this is prevalent in 12.0.0 as well), our SolarWinds.InformationService.ServiceV3.exe (henceforth referred to as SWISv3) memory usage went from averaging 800 - 1,000 MB to now averageing 2.5 - 5 GB. However, despite the higher memory usage this doesn't seem to effect anything until occasionally the SWISv3 process will jump up to using 15 to 25 GB and we will start seeing problems. I don't know if it is related, but in the SWISv3 log files (located at C:\ProgramData\SolarWinds\InformationService\v3.0\Orion.InformationService.log) there are nearly 30,000 lines in which virtually all of them are the following:
[EasyNetQ consumer dispatch thread] WARN SolarWinds.InformationService.ChangeBroker.Broker - (null) (null) Change indication for Orion.APM.Component is missing values to provide in a notification, but additional query returned no matching entity. Please check the validity of key values in the indication reported.
With the occassional few lines of this sprinkled in:
[EasyNetQ consumer dispatch thread] WARN SolarWinds.InformationService.ChangeBroker.Broker - (null) (null)
Change indication for Orion.APM.SqlDatabase is required to contain {ItemID, ApplicationID} key properties, but {ItemID} missing.
Currently the 20 previous Orion.InformationService.Log files in the directory are 10,241 KB each... So over 10 MB of these EasynetQ log entries in each log file. I'm posting this on Thwack and not a Support case because there doesn't seem to be any directly attributable issues I can point to because of this, so I wanted to see if other users are experiencing the same issue and/or if a SolarWinds employee (like aLTeReGo perhaps) has seen this with other clients and can comment on this? I don't think this should be normal behavior and I'm also concerned about the exponentially larger memory usage of the SWIS service with the new version. I haven't installed the newest Orion Core hotfix that is out now, but reading the notes for it I don't see anything it will fix that has to do with this, so I'm not sure what kind of difference that will make.
