Hi, This error may be just cosmetic, but with posix-locks loaded on the server side, I get ENOTCONN instead of EAGAIN when trying to establish a conflicting lock. According to the trace translator, posix-locks works fine on the server side, it sets errno to EAGAIN. However, on the client side something transforms it into ENOTCONN. Here's how I tried it: <server> storage/posix debug/trace <--- errno is correct (EAGAIN) transport/server (tcp/server) <network> transport/client debug/trace <--- errno is ENOTCONN <client> Are you aware of this? Is this error significant? (I guess it is, since EAGAIN is a temporary error instructing the caller to retry the operation, while ENOTCONN looks like a fatal one.) Thanks, -- cc
