In a similar vein, trying to reconstruct a reported error from application logs or crash dumps is, in my experience, murderous when combined with interruptions.

In a similar vein, trying to reconstruct a reported error from application logs or crash dumps is, in my experience, murderous when combined with interruptions. You're trying to piece together why this unexpected error occurred, cross-checking source code, multiple log files, screenshots, and fragmentary narratives provided with the report, to build a mental model of what the state of the system was when things went south. Then somebody pings you with some completely unrelated urgent thing, and poof! goes your mental model out of working memory.
