This read-only counter tracks how many times a request for storage from a given pool could not be satisfied because there was not enough space available, and being a Counter type it has no defined starting value though the recommendation is to initialize it at zero. A rising count here is a direct signal that the printer's memory, RAM or a resource-saving pool, depending on which row, is running short for what is being asked of it. For instance, an admin who sees hrstorageallocationfailures climbing on the PostScript resource-saving pool would know that PDL is repeatedly failing to get memory it needs, likely because too little resource-saving memory was allocated to it.
