I didn't see anything that screamed SystemTap to me, but here's one that I thought might be applicable... Subject: Size-128 slab leak http://lkml.org/lkml/2006/1/30/387 This was followed up later by a patch to detect slab leaks. http://lkml.org/lkml/2006/2/2/47 One could probably write a quick SystemTap script that does the same thing as the given patch, without needing to recompile the kernel. Simply put a probe on the point to instrument (within slabinfo_write) and use embedded-C to walk the structures and report the same information. On a related note, it might be nice to put together a BKM for monitoring the LKML, or at least hear others' methods for doing so. I found it difficult to sift through all the traffic, so I'm wondering how others have been going at it... Thanks, Josh
