Hi David, We faced a network outage this week and as a result, our 4 servers using cachefs went in a very bad shape. Even when the nfs-server came back and while I was able to log in the server and browse the nfs mount, the whole cachefs part was ****ed-up. Appart from this failure, we have not seen any problem for the past weeks. Attached trace2.txt from one of the failed server. (running debian 2.6.32-4-686 kernel with all your patches). Hope this may helps Regards, -- RD
