HiEvery now and then my SCOM throws up "Information Store: Version buckets allocated - Red(>2000)."Does anyone has any idea on this. I've visted Ms and other blog sites but unable to find a resolution. Is it related to online defraghmentation?Please help me curb these alertsExchange Server 2007 - SP1

Thanks Amit, is there any way this could be increased? It just shoots up above 2000 for few seconds,an event gets generated and comes back to normal.By the time an engineer checks on the server the problem seems to be back to normal.Very finikcy indeed

Hi,After you follow somesteps to try toresolve the problem,please close the alert in SCOM and wait to see if the alert will appear back again.If yes,then please run ExBPA to have a health scan and then check the report.Also I recommend you to check the event log and then post the detail error event here.Related information to share with you:Large Message Processing in Exchange, Part 1: Prevention and Planning http://msexchangeteam.com/archive/2009/07/07/451737.aspxRegards,Xiu

Are the alerts firing overnight during online maintenance and then closing? Then its probably related. I see these all the time during maint.

Yes exactly, these are fired whenin between online maintenance periods. My disk throughputs,system memory and storage are all ok with no serious issuesin Exbpa reportI probably should disable this from SCOM, what you suggest??

Personally, I wouldnt disable it. If it fires during the day then it might be indicitive of a problem. What I like to do is add Company Knowledge to the alert stating something to the effect that "If these alerts fire during online maintenance and then close, then its ok to ignore, etc..."
