Hello Benjamin:
I am using Imagemagick.
LocalSettings.php:
---
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = "/usr/bin/convert";

I have noticed that the free memory drifts downward with time.
Here is 'top' at different time points today:

The first problem was around August 20: I had zombie processes alert
and needed
a server reset. That was a first. I assumed it was isolated and things
were okay until approximately August 28.
I have automatic security updates from debian. My 'apt' log shows
upgrading of php & apache on August 21 and 22. I don't see any other
significant updates.
This problem is quite frustrating. I am happy to hear any suggestions.
Thanks,
Michael
