In such cases I tend to go "low-level" where I eventually using "strace
-fp PID" on the running process (redirect stdout/stderr to a file, do
not leave it on the terminal).
This provides more insight to things happen. My last suprise was an
ativated Linux security extension (SE-Linux) which prevented a slightly
reconfigured daemon from accessing a directory not known to SE-Linux.
SE-Linux still allows a program to check if it is allowed to access a
filesystem object (access() systemcall) but on the actual operation the
access has been denied.

Just one thought ... not necessarilly connected to to the stated problem.
