It's probably a combination of data and block growing together along with the occasional estrdup that is causing the fragmentation. You should rewrite both of the reallocs to double the array when they outgrow the current one instead of growing by a fixed amount. The fixed amount is nice because it avoids the extra variable tracking the maximum size of the array, but it's a terrible algorithm. Russ
