So I have some more information on this problem.
I have say 9 checkouts occurring simultaneously. Load is up to around
10. Each process has about 9-10% CPU, and has a state of run. Files
are being written to the clients at about 30MB per min.
As soon as I start an import for a 10th simultaneous svnserve process
all process assume the sleep state and drop down to 1% CPU or less.
Load drops to 1-2.
The import is killed mid stream. All remaining svnserve processes
performing the checkouts remain in sleep state. While in sleep state
files are written to the clients at a rate that nonexistent.
Any ideas on why this might occur and how to prevent it?
