You probably should look at the section on debug in the handbook. At a minimum, you need a kernel built with "makeoptions DEBUG=-g". Other than a bit of disk space and a few seconds while building the kernel, this costs nothing and should always be in the kernel config; not just when you want to look at a problem. You also want the KDB, DDB, and GDB options in the config. These also have no impact on performance, but do eat some memory. Since this looks locking related, WITNESS is probably a good idea, but it is a big performance hit. I'd also add INVARIANTS and INVARIANT_SUPPORT. The cost of this is much lower than WITNESS, but it's not free, either. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
