Unable to use dotMemory profiler with Sophos Endpoint enabled

Environment

• Microsoft Windows
• Sophos Endpoint
• JetBrains dotMemory

Problem

When attempting to run a profile scan using JetBrains dotMemory, the process fails to initiate or hangs indefinitely ("nothing happens"). dotMemory shows 0 memory in use.

Cause

This behavior is caused by a known conflict within the Sophos Endpoint software. The standard file-path exclusions are usually insufficient because the conflict occurs within the event monitoring logic rather than simple file access scanning.

Resolution

To resolve this issue, one might try the following workarounds:

• allowlist dotMemory executable and make sure that dotMemory is allowed access to %temp%, %appdata%, %localappdata%
• exclude dotMemory from "Monitor Domain Controller Events"

Depending on the environment, this change might be insufficient and one might need to additionally exclude dotMemory from "On-Access-Scans".
