Don't ask me, my knowledge about the VM system is too poor either. ;) As i've kept it in mind, the problem is that INN is doing something that is illegal with an mmap()'ed file, hence there won't be a real kernel fix for this. (The SVR4 implementation of mmap() doesn't stumple across this bug since they don't have a unified VM/buffer cache. Again, this is from memory, mistakes are mine.) I'm not sure whether anybody in the INN camp is tracking this. To the best of my knowledge, there are several independant threads of INN maintenance, but i have no idea what they are doing right now. I once fixed a bug in the INN-internal Xref generation, and tried to submit this fix to both, Rich Salz, and the INN-unoff maintainer. I haven't heard anything back... -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
