Sorry if this isn't as informative as necessary. Please feel free to ask for more information. It appears there's something of a memory leak, as I reliably get this after Webstorm has been running for some time. The "a Week or Two" in the issue title is an estimate. The listed stack trace was today, the last instance occurred on the 17th of this month and before that I saw it on 2017-03-06.
The painful part of this is that it locks up the IDE for 5 minutes while it crashes.
