All 5.2 versions have this problem.

Hi, I was hoping someone would have an idea of what's going on here...
We have two NFS issues. One of which is certainly centos based, one of which we're not sure of.
First issue is: As of Centos 5, we can't make simultaneous access to a directory via NFS. To duplicate, I cd into a share in two windows, copy
a
1G file in the first window, and just do an ls in the other. The ls will hang until the write is done.
Turning off apic seems to help a little, but there's still a very significant hang.
This problem is not apparent in centos 4.x, even when mounting to the
same
NFS server.
The other problem is - we're seeing tremendous slowdowns when going
through
an Acopia NFS virtualization server. These slowdowns got much more
severe
when we moved to Centos 5.2. If we connect to the NFS appliance
directly,
these slowdowns don't exist.
Has anyone seen problems like this? How did you solve them?
What is the version of your kernel? There are (used to be) known issues with NFS in certain versions of the CentOS-5 kernels.
