When I worked in telco we used to run into this a lot. We'd demand standard alarms for things like memory leaks / out of memory conditions / high than normal memory usage, as to get 99.999% uptime we want to be paged when problems like this would occur. Except a bunch of platform did the extremely naive implementation and included recoverable memory in their alarm conditions. So inevitably someone would log in and grep the logs or copy some files to the system, and hit the alarm conditions. And there were some vendors who really didn't want to fix it, they would argue that recoverable memory is in use, so it should really be part of that alarm condition.
