FMS 11 Memory leak during backup

Your post

We seem to be experiencing a memory leak when FM server backups its databases. It's completely repeatable I'm just not sure how to fix the issue. The bigger problem is I'm not a database admin and only have limited experience with FM 6 up until our move to 11. The deal is we are an Optometry practice and we run the Maximeyes practice management software at our company and usually all our support for Filemaker is handled by the software developers. However, they don't seem to have an answer to this memory leak issue so I'm posting here in hopes of an answer. The only thing I did get from them was to check the cache dump size on the server, which I did but they have not gotten back to me on how/if I should adjust it. Right now 'RAM reserved for database cache' is set to 64mb and the 'Cache flush distribution interval is set to 00:01.

  • FMS
  • Dell PE R710
  • 2008 R2 x64 OS
  • 12 GB memory

I have not observed what happens during the backups but right after the backups have run, the system memory is completely used up. As soon as you stop and start the filemaker services, the memory is released and all is normal again. This appears to happen every night when the FM backup runs. The backups run when nobody is on the system of course and no other backup of my own or any other kind of process is scheduled to run when FM is doing its backup.

Our FM/Maximeyes system contains 52 databases totaling 10.7 gigs with the largest single database being 2.2 gigs in size. There are 3 databases below that at 1.6, 1.6, and 1.3 gigs in size. The rest are below 1 gb all the wa down to a few megabytes.

Any ideas on how I can troubleshoot this? Again, not a database admin or very experienced with FM. About all I know how to do is run consistency checks/repairs on the databases.
