File creation problem - cache?

[Ian Collins]

Am I going mad, or does this sound familiar to anyone?

We have a process that,

1.1. Creates a file
1.2. Populates the file 
1.3. Closes the file
1.4, Forks a new process (with the filename created above as an argument).

The child process,

2.1. Looks for a file specified as an argument.
2.2. If found, reads and processes the file

We are seeing, time and again, that the child does not find the specified
filename.
However, by putting a delay between 1.4 and 2.1, the problem disappears.

Is there a caching problem?
Can anyone suggest a reliable work around?

(Or am I just going mad).

Ian Collins.
