All, Since last 4 hours, our file descriptor drop. Usually, the FD usage is around 700 - 800, but now it becomes 1000-1200. I remember that our FD ever dropped abnormally, then we found that NIMDA cause the problem. Now, I cannot get the source of problem yet. Would you tell me what packet / request that consume FD? Thanks a lot for your help Best Rgds, Awie
