TCP Resets

I've just inherited an HAP network.
On all of the servers that are load balanced I'm seeing a ton of RSTs from HAP. Everything appears to be working just fine, but it seems abnormal to me that HAP would terminate every session via RST instead of FIN. I've tried unsetting abortonclose in case that was an issue, but it didn't change the behavior. Is this normal behavior? If not, what configuration might be causing it? Running 1.4.9 on Linux 2.6.18-194.26.1.el5
