Thanks for the feedback. It looks like there is memory leak issue with older 3.6 ver of BES that does not close the mapi sessions for EX2003 servers and always keep the messages open at their max default which is 250. You can increase the limit, but you're essentially letting your server be more vulnerable to degradation, that's how I see it. I read a thread about a user who increased the limit to 2000 and BES would eat it up to 2000 and never close the session. After checking these users, they are on the EX2003 servers and using BES 3.6, and BES logs seem to indicate the memory issue, so I think we're on the right track. http://www.blackberry.ru/knowledgecenterpublic/livelink.exe/fetch/2000/8 021/8149/8064/Support_-_Memory_leak_results_in__ERR_RESOURCE_ALLOC__erro r_and_truncated_messages_on_BlackBerry_Handhelds.html?nodeid=767441&vern um=0 ________________________________ From: Nardini, Steve [mailto:Steve.Nardini@xxxxxxxxxx] Sent: Wednesday, March 22, 2006 12:24 PM To: Chong, James Subject: RE: [ExchangeList] Re: User does not exist! I'm not totally sure what your issue is, however I saw a couple key words and brought to mind a problem I've had before with Exchange. Was just reminded of it this past week also. Maybe this link will help with your problem. http://support.microsoft.com/?kbid=830829 <http://support.microsoft.com/?kbid=830829> Steve Nardini IT Support Specialist Gray Plant Mooty 500 IDS Center 80 S 8th Street Minneapolis, MN 55402 612.632.3272 Direct 612.632.4272 Fax Steve.Nardini@xxxxxxxxxx ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of ChongJa@xxxxxxxxxxxxxxxx Sent: Wednesday, March 22, 2006 11:04 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: User does not exist! I'm thinking BES has something to do with this. Although I cannot locate the user, this server is the only server has mailboxes with 250 open messages via the BES service account. My question is doesn't BES release the messages after it scans these BES user's mailboxes? If not this would surely degrade performance having many BES users. ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Chong, James Sent: Wednesday, March 22, 2006 10:06 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] User does not exist! Getting event id 9646. I'm not so much as interested in the event, but the user it talks about (user37534619) does not exist, and cannot find him anywhere! This event for this particular user started last Saturday and has repeated every 30mins. I went through every store on the particular ex server, do not see this mailbox, searched through AD, LDAP queries etc. Mapi session "/O=American Red Cross/OU=ARCHQ/cn=Recipients/cn=user37534619" exceeded the maximum of 250 objects of type "objtMessage".
