Coda File System

Checkpointing causes local/global conflict ?

This is a Darwin issue, that I need help with again.

Quite frequently, we get a local/global conflict while writing data to 
coda. This happens when there is only one client involved, so there is 
no real cause for a conflict.

It seems to happen if a write coincides with venus making a checkpoint.

Is there any way I can turn off automatic checkpointing? In that case, 
I'd like to do that and run som stress testing operations to see if 
turning it off helps.

Then, if turning it off helps, should there be any kind of mutex in the 
kernel module to serialize these operations ?
