What are you seeing that identifies it as a kernel process? The only way I know of determining that from ps is "ps axlo flags", and looking for processes with the 0x200 bit set. > clamav 1568 0.0 1.8 37592 37008 ??

Any thoughts ? ps or libkvm out of sync with kernel? kern.ps_arg_cache_limit set to 0 for some reason? -- Dan Nelson dnelson@allantgroup.com
