I spent now the last three days trying to figure out whether my custom conf= ig is faulty or CURRENT has a serious bug. Even with GENERIC and in single user mode (it= takes then longer) CURRENT, now at r307823, is crashing. The crashes seem to be unrel= ated to X11, but I can trigger this crash faster when using firefox. I also can trigger = it faster when doing a "svn update" on a ZFS pool containing /usr/ports. Everyone who uses= ZFS on /usr/src or /usr/ports and updates via subversion knows that over time t= he update process takes 10 - 15 minutes on ZFS volumes - compared to several minutes = on UFS. And while svn traverses the folder /usr/ports, the crash occurs. I'm still wondering about the fact nobody else is facing such a periodicall= y crashing. The crash is, I already reported this, with CURRENT on several boxes with o= r without ZFS. How can I track a memory leak? How can I write to disk the backtrace given by the debugger when crashing? = My box I can freely test is using the nVidia BLOB and vt(), so I can not see the backtra= ce. I got a very bad screenshot on one of my laptops, but its so ugly/unreadable, I thi= nk it is unsuable to be presented within this list at a reasonable size (200 kB max = ist too small). --Sig_/R.u+dO9C5.vTo_05aRUiKoi Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEcBAEBCAAGBQJYDOREAAoJEOgBcD7A/5N8MbsH/iN4jAEKYGvBd18wtjt4F7b1 8vCDVZ52bOICsp5d+1M1d+J1KZhdvh12Wr04ClBAOMuvkHRgDENaccZHrxruoEBQ rcjHBrfJgiwluMLdS0kmGM0bjjQo/+bTGj4nFrW1FNPcrQyPfyEw+Lko7BncX7sR vTWlup+li3kI1/J1NwImPYipl6y821vUjJNZ4bQVVBobtJ5rKxT64S6qg6Y8zV/C +3Cc66QV54T2AONhNdCWUfIcJ4TvAZPdJl4d3nCvTZv2mS8SpAXbWeQoPUKSSoyG ybOkIoCJ8GtjdH+/E8KA0MfZ60xPtQWBxImz3h/WIQ9dp3IYdW7J8+yGgpv5gCs= =B63N -----END PGP SIGNATURE----- --Sig_/R.u+dO9C5.vTo_05aRUiKoi--
