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.

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
