I'm guessing that this is because we neither hold the lock or get
reference to server struct while we print these dynamic tracepoints.
I fixed some of these by using local variables in my crediting
patches. We should do it for others too.
Let me spin a patch for this today.

Shyam

Correction, we should be having a ref to the server struct.
And it doesn't look like we free server->hostname, unless we have
dropped the ref to 0.

The call trace does seem a bit odd. I initially assumed that this came
from a regular file read.
However, I see some unexpected function names.
Is a procfs read somehow triggering this?

Needs more digging.

Regards,
Shyam
