Our server processes 50 thousand emails daily (of which 30,000 are local). This machine is configured with Raid 5 (4 X 72 GB SCSI 10 K rpm). This machine has windows 2000 advanced server with Exchange 2000 Enterprise installed. We have applied famous 3 GB switch in boot.ini file. This machine has 36 GB of its Exchange Database size (.edb and .stm files). The problem with this machine is that normally it processes emails at very high speed but at some time (once in 24 hours) messages stuck in its local queue. After that messages in local queue keeps on increasing. This problem gets resolved when we restart Information Store service. Sometimes we have to restart whole machine as well. Mostly we have observed that if we restart this machine once in 24 hours, this performs well. We have checked its event viewer but didn't found anything unusual. There are no such events in event viewer some thing like that " Virtual memory necessary to run Exchange services is defragmented in such a way that now you need to restart your services, etc.". If any body help me, it will be so good. Thanks and Regards in advance, Regards, Muhammed Ilyas ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: raj.periyasamy@xxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
