This should *not* happen. What did we (I mean developers) do? Don't know, on my 2.6.9-skas3-v7 host it doesn't happen. And on the 2.6.7-skas3-v7 it doesn't also. Not in SKAS and not in TT. By the way: why should SKAS produce lots of zombies? Maybe in TT we could have missed something, but in SKAS I can't see any possible reason. > >>This is on a 2.6.7 host, using your >>host-skas3-2.6.7-v1 patch. > > ???

I tested on 2.6.9 and 2.6.7, but not on 2.4. For info: my latest patch, as included in bb3, changes more than necessary. I tested, which parts of the previous patches from BlaisorBlade and me really are needed. But the tests were wrong, since I missed the fact, that make doesn't work correctly for USER_OBJS. Thus I had a inconsistent kernel and saw UML exiting in boot. Since UML accidentally worked fine after inserting a further part of my changes, I incorrectly assumed this part to be needed. Thus, Jeff posted a new, further stripped patch with the subject "The current fix-kill patch". It has to be applied on top of BlaisorBlade's "uml-hang-on-2.6.9-host.patch". I have tested this again, with hosts 2.6.7-skas3-v7 and 2.6.9-skas3-v7 in SKAS and TT. For me it works fine.
