Internet Explorer 11 process is leaking memory. This issue affects all ServiceNow releases and all websites using iFrames.
Steps to Reproduce
- Open a ServiceNow instance in Windows IE11.
- Open the Task Manager.
- Monitor resource usage.
- Click various modules and gauges (for example, System Diagnostics, Service Catalog, Knowledge), always waiting for pages to finish loading.
- Repeat steps 2 and 3.
Note that memory usage climbs.
For instances not using the List v3 plugin, a partial fix was deployed in Geneva Patch 10, Helsinki Patch 6, and Istanbul for KB0598416: Using AMB Client on the parent frame from the contained frame causes a memory leak in IE11.
For instances using List v3, the best option is to upgrade to Istanbul where performance and memory leak fixes have been deployed.
