I’m seeing some strange output from the pmp-check-unix-memory check. It’s reporting that 10% of the overall memory is in use, but that 102% of the memory is in use by the mysqld process. The server is running Debian Squeeze. Has anyone seen this before?

From this output I see mysqld reports VIRT (virtual memory) 16.1g. And it is 102% from the total RAM. You can disable the plugin from checking the largest process in the memory by using ‘-d’ option. This way the plugin will report the correct status.
