This is giving problem to me
Before I open this log file I noticed that the FD0 is points a pipe , may be the pipe gets closed when it comes to cleanup_register
The problem arises in following scenario
- This changes my Apache parent process FD 0 to open to this log file.
- Later the file is got removed , but still FD 0 points to removed file.
- Some part of my code assumes that FD0 is STDIN and tries to open this and fails with error "Stale NFS file handle"
As you suggested if i open a dummy file handle , this issue is solved.
is my assumption is wrong "FD 0" is reserved for STDIN ?

If you have closed FD 0, the next file opened will get that file
descriptor. If that's the case, one solution is to open /dev/null
after closing FD 0; another is to just let the FD be 0, as long as it
works.
