I've never seen an event log entry on one DC complaining about the memory on another DC, although I suppose if one of the RPCs returned an out of memory error, you might get that. Do you know what process is sucking the memory? Is it a transient issue? Depending on the size of your DNS zones, DNS can use a lot of memory at startup. -g From: ActiveDir-owner@mail.activedir.org [mailto:ActiveDir-owner@mail.activedir.org] OGil n Behalf Of Sabharanjak, Ravi BGI SF Sent: Tuesday, August 19, 2008 11:00 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] Not enough memory event log message. How much RAM on those DC's? In our environment, we have 4 GB of RAM at least on the DC's (Win2k3 SP2). This leads to a condition where the LSASS grows to it's max limit of 1.8 gb on a 32 bit system, and then is not able to allocate memory for replication. Per Microsoft, our options then are to either reboot the server or shrink the LSASS working set by either running a backup or run an unsupported Microsoft utility on a schedule. We now run a backup every night using a ntbackup script and keep about 7 days worth of backups locally. If there are no obvious memory leaks, try running a ntbackup on the DC's and see if the replication kicks back in. -Ravi ________________________________ From: ActiveDir-owner@mail.activedir.org [mailto:ActiveDir-owner@mail.activedir.org] On Behalf Of Steve Schofield Sent: Tuesday, August 19, 2008 10:30 AM To: ActiveDir@mail.activedir.org Subject: Re: [ActiveDir] Not enough memory event log message. I had a domain controller boot up after patching this weekend and logged "Increase the amount of physical memory or virtual memory and restart this domain controller." right after the DC came online. The error was referring to the destination domain controller. For example, I have DC1 and DC2. I rebooted DC2 for patching and when DC2 came online, the error showed up stating DC1 didn't have enough memory. I looked DC1 memory and there was 100 MB of memory free, the commit charge was less than 50% used. I'm not certain if adding more memory to DC1 would resolve the issue. I've not seen any other replication issues since and this is the first time I've seen this error. Google is not being too helpful. From what I can tell, AD is having no issues. Both DC1 / DC2 are Global catalogs and host DNS services. Thanks, Steve -- This message and any attachments are confidential, proprietary, and may be privileged.
