Are you using multipathing on your server for storage?
Are you using EMC storage?

Dear list:
I am investigating a process 'MpxTestDaemon' on a Linux server (RedHat 6.9 as I
recall).
This server is running Oracle 12.1, and has 1.5T of RAM.
It is a standalone server, not RAC.
There are some anomalous things occurring with this process.
For instance, at times pidstat reports impossible numbers of minflt/s (mem
faults not requiring disk access) being performed: approx 1.85 * 10e18
Right now though all I am asking is this:
Does anyone know what this process is?
Neither Oracle nor the Google have anything helpful.
In Oracle's case, no references at all.
In the meantime, I shall see if I can find out what it is doing.
Thanks.
