The lock that message refers to is in GetVCache. This suggests that you're thrashing the vcache - as Jason suggests I'd take a careful look at your cache statistics. I do have some longer term plans for ways of decreasing the contention here. Apache really likes the stat() command, and if we could find ways of reducing the locking necessary to return results to stat(), web serving from AFS could be substantially faster.

I suspect that the work that Derrick did on dynamic vcaches will help with this particular case, as it should move cache flushes away from the kernel thread that's actually doing the access.
