Mezzmo service and high memory utilization

**jbinkley60** · 11-16-2012, 07:55 AM

I run Mezzmo 2.7.1 under Windows 7 X64 Pro on an 8 core AMD processor machine with 32 gigs of memory. I've been noticing that when the machine boots up, it will often show 20 gigs of memory in use. After some troubleshooting I found that the problem was related to the Mezzmo service. If I shut down the service I could immediately see the In Use memory start dropping in the Resource Monitor until after a few minutes it was down to 2.5 gig in use. After some additional troubleshooting I found that if I changed the servcie starting from Automatic to Automatic - Delayed, it would start normally (after a short delay) on reboot and would use a normal amount of memory but with Automatic the service would chew through available memory. It ran fine, even with the large amont of memory in use but it shouldn't be doing this. Anyway, I am set to Automatic - Delayed for the service starting and memory usage is normal now.

I spoke too soon. After a few minutes of the service running under Automatic - Delayed it did the same thing and chewed through 20 gigs of memory. It just took longer than Automatic.

A set of logs files should help tell us what could be the reason for the high memory usage. Please turn on logging (see http://forum.conceiva.com/showthread...nostic-logging) and restart your Mezzmo server. Wait about 5 minutes and then stop your Mezzmo server and exit Mezzmo. Zip up all the logs and send them to us at support [at] conceiva [dot] com.

Paul,

As always, thanks for the superb support and quick turnaround. Unfortunately the patch didn't fix the issue. I just zipped up another set of logs to you.

Thanks,

Paul,

I just sent a note to support. It looks like the culprit was the Microsoft Superfetch service. I found it by disabling the Mezzmo service and 5-6 minutes after a restart I saw the same condition. I kept disabling sevrices and doing restarts until I found the Superfetch services casuing the issue. It is disabled and Mezzmo is running. I am now seeing 7% memory usage (~3gigs).

Thanks,

Jeff

Hi Jeff,

Good troubleshooting & thanks for confirming all is OK now.

Hi, I have been following this thread but I have exactly the same issue since upgrading to 2.7.1.
I run XP SP2 and prior to upgrade the Mezzmo service ran in around 57Mb memory. It started this morning at 207Mb and is now 301Mb (4 hrs later). Any ideas what might be causing this memory ballooning as XP doesn't have superfetch?
