[Lustre-discuss] ll_glimpse_size() causing intermittent EIO

We're seeing a problem recently with a 1.8.4 server and both 1.8.2 and
1.8.4 clients. We get intermittent log entries on the client like this:
LustreError: 32493:0:(file.c:995:ll_glimpse_size()) obd_enqueue returned
rc -5, returning -EIO
Occasionally we get "rc -4" instead of -5. The client code fails with an
I/O error, as you'd expect. We can't find matching log entries on the
server.
Trying the same file on the same or different clients again a few
minutes later works fine. We're seeing this on lots of different clients
but intermittently and fairly rarely, but it obviously it tends to crash
user jobs. Any ideas what could be causing it?
