When the assistant runs lsof on my file system, the lsof process consumes a horrendous amount of memory (>11GB). This forces a large amount of swapping, and brings the system to its knees until the process exits. The same thing occurs when I run lsof manually, but this is currently making the assistant unusable for me. Is this normal when running lsof on a large number of files, or is something wrong with my particular setup?

An example of resource usage from top, and some system details:
