[OpenAFS-devel] How can the mem cache possibly not be able to allocate memory?

[Derek Atkins]

IIRC it's an order-of-magnitude problem.  If I recall correctly, the
amount of ram that's allocated in a memcache is much larger than you
would expect compared to a disk cache of the same configuration.  I
seem to recall you should div-10 your number to get a reasonable
memcache size.
