OpenSSL will only "open()" and "read()" from the file.
Please run trace/strace/tusc/truss or whatever the system call tracer
is called on your platform and see, whether the open() or the read()
call fails and with which error. This already should give you a hint.
As far as I have seen from the open() man-page, using a named pipe for
this purpose is not very robust (it will fail for non-blocking behaviour:
you cannot open a pipe for writing without a reading process, HP-UX 10.20)
and I am not sure how this setup should work with several processes
trying to read entropy at the same time.
Best regards,
Lutz
