You can clearly see, that even though kern.openfiles still > shows a high number, pstat -f only finds very few files. Ahhh crud - the kern.file sysctl isn't completly calculated from the list of all open files - it iterates through all the processes to form the final list. Could you try rerunning pstat with the patch below - it walks the full open file list, rather than checking each process (this may leak open file info to people within jails on the machine, hopefully that is not a problem for you...) (You'll need to recompile your kernel, but not anything else...) If the files start to show up here, then we can begin to figure out where they're comming from. David.
