PHK, could you tell me more about your system? Are you >running anything special, that I can reproduce the problem? HP800 laptop. 48M Ram. Pretty much vanilla -current. For instance, I use mh to read email. the "inc" program will often sigbus when I have been running something else and rerun it to see if there is new email. It looks like some page gets stolen, and the object isn't updated accordingly... >Note that the new code follows the "rules" fairly precisely regarding the >vnode free list. Some parts of the system might not be able to deal with >it yet (maybe.) But this would be related to pages, they die with a pagefault... -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
