In Windows Task Manager, in the Processes tab, what does I/O Other mean?

In Windows Server 2003, I'm seeing a process in Task Manager with a high value in the I/O Other column. I'm trying to determine if it's in some kind of error state, but I don't know what I/O Other means. I/O Reads and Writes are low. What is I/O Other?

I'm also looking for any more detail I can get on what an I/O Other operation is, more explanation than "An example of this type of operation is a control function." Thanks


Solution 1:

According to TechNet:

The number of input/output operations generated by a process that are neither reads nor writes, including file, network, and device I/Os. An example of this type of operation would be a control function. I/O Others directed to CONSOLE (console input object) handles are not counted.

If you need more detailed info than Task Manager provides, take a look at Process Explorer and Process Monitor from Sysinternals.
