<div><font color="#1F497D">I'm experiencing below pluto failure with openswan-2.6.21-5.el5_5.3 when I was trying to stop ipsec during traffic. According to searching result from Google, it looks this kind of issue happened before with older openswan release.
But I could not understand what's the root cause and solution for that. Anyone knows the root cause and solution?</font></div>
