Johnson, Edward A. :
Turned out to be a balance issue between the number of pollers,
the vm.dirty_background_ratio, and the vm.dirty_ratio.
If I recollect, many distro come "teaked" for end-users, so with both
values too high with plenty of RAM servers.
Usually on servers that aren't file server, I set :
vm.dirty_background_bytes=67108864
vm.dirty_ratio=10
Edward, can you specify your sysctl values, kernel, distro that are not so
good for that server ?
There are many different configs, I think it is useful to report the
"guts" of the problem.
best regards, Sala
