Note that the linked article is from 2004. The kernels that RedHat uses are a
bag of hurt, not to mention ancient.
If you can upgrade to RHELl5 that may be the easiest fix (I can only assume
that the mmap limitation has been removed). Perhaps RedHat has newer RHELl4
kernels in a bleeding edge
amd64 refers to the architecture (AKA x86_64), not the particular CPU
vendor. (As a matter of fact, I was unaware of this limitation;
AFAIK it does not exist in FreeBSD.)
In any event, mmap()ing 340GB even on a 64GB box is a recipe for
disaster; you will probably suffer death by paging if
Thanks.
I checked /proc/cpuinfo and it shows intel processor.
So even with Intel, we see this limitation of 340 GB. This is a
serious limitation to me, since in Squid, we were using 1.5 TB of
storage and i thought i could mmap and use all the space for Varnish.
Any workarounds or working kernel ver

| 1. varnish doesn't send IMS request, when the object expires.
Correct. This is somewhat hard to do, but we see the request coming in
regularly so it's something we might want to change at some point. I
don't believe there is any way to achieve this using VCL.

help with my questions.
