Thanks to all who responded,
It seems that it is not Apache causing the SA but the reading & writing to
pipe files that I'm doing. The patch is STRFDC5 for 6.0 that fixes it, it
solves SA 1047 (which is the one I'm getting) and SA 818. This problem is
fixed in 6.5.
Thanks again for the many prompt responses,
