RE: [ActiveDir] Security Log file size not reaching the maximum log file size

And just so you do not think I am making this up here is the public reference that documents it: http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/TechRef/5a86ab0f-c7eb-45ed-9e5e-514173bf15e3.mspx :-)   Thanks,   -Steve   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steve Linehan Sent: Tuesday, October 18, 2005 10:45 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] Security Log file size not reaching the maximum log file size   This problem is described in http://support.microsoft.com/default.aspx?scid=kb;en-us;312571 .  The fix allows the automatic archiving of the log files but does not explain why the problem occurs.  The issue is around the fact that a contiguous block of memory is needed for all of the log files and this is not pre-allocated so if the memory on the box becomes fragmented, which it will, then eventually the contiguous block can not be allocated and we will stop logging.  Generally we recommend not setting the total size of all logs over 300 MB and using the feature above for the security log so that it can be automatically archived.     Thanks,   -Steve   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, October 18, 2005 8:54 PM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Security Log file size not reaching the maximum log file size   We recently increased our auditing and set the security log file size to 1G, but the security log over-writes at about 409MBs; thus never reaching the 1G security log file size.
