Thanks. A couple things: 1) Can you perform the same pkg_delete but with the -v flag? This should cause quite a bit more output, but will help track this down. 2) Output from cat /var/db/pkg/linux-tiff-3.7.1/+CONTENTS 3) Can you put the below files up someplace on the web, preferrably in a tarball? I'd ask for them, but the mailing list strips attachments. I'm wondering if there's some binary data in one of the files (e.g. interested in why +CONTENTS has a newer mtime than +COMMENT and +DESC). Have you had any filesystem problems as of late? dmesg -a show any filesystem issues or disk issues? > Oh and here is the content of /var/db/pkg/linux-tiff-3.7.1: > > total 40 > -rw-r--r-- 1 root wheel 32 Mar 17 2007 +COMMENT > -rw-r--r-- 1 root wheel 4098 Jun 8 14:21 +CONTENTS > -rw-r--r-- 1 root wheel 229 Mar 17 2007 +DESC > drwxr-xr-x 2 root wheel 512 Jun 9 11:05 . > drwxr-xr-x 700 root wheel 27648 Jun 9 22:29 .. The code in usr.sbin/pkg_install/lib/plist.c which is causing the segfault: 462 if (p->next && p->next->type == PLIST_COMMENT && !strncmp(p->next->name, "MD5:", 4)) { 4) What date are your system sources (specifically src/usr.sbin/pkg_install)? The reason I ask is that there were some recent speed optimisations applied to the pkg_* tools, and I'm curious what "version" of the sources you have. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
