I've got quiet the same problem (perhaps!): >From a PHP page I call a C program on the server using the passthru command to create a RRD file. The rrd_create() function from librrd creates the file but with a size of 0, and the rigths of the files are strange: sometimes tey are -r-S--S---, if I execute once more they can be -r-S--s--- or something else, depending on something but what????? I found out something strange (perhaps you can see the same behaviour in your case): The command array passed in parameter to the rrd_create function is changed by the fonction (order of elements in the array are changed) is it normal??? I didn't find a solution to my problem. I'm going to try to use the system() system call in my C program instead of librrd and I come back Bye DP
