-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, It seems that we have a potential livelock during coredump on 7.0-R, the case was that two processes trying to coredump in the same time (e.g. if I configure kern.corefile=/var/tmp/%N.core and a lot of instances coredump in the same time), perhaps when paging involved with it. Upon reboot, it would not recover but wait infinitely. The box is running 7.0-R/i386, UP (Origin = "GenuineIntel" Id = 0xf34 Stepping = 4). Is this an known issue? This is my own server but I do not have my hands on it because it is in China, however I can provide some help if the experiment can be recovered with a power-cycle :) Cheers, - -- Xin LI <delphij@delphij.net> http://www.delphij.net/ FreeBSD - The Power to Serve! -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkgVYg8ACgkQi+vbBBjt66DTMQCfXQ4q327phAzDeEmUhtgUoJxS Ap8AniSdbCY0HN9m5wf9nAbKyLFifUQg =V94G -----END PGP SIGNATURE-----
