Hi list, I have some problems with one of my FreeBSD installations. I am not shure if this the correct list, but I hope so. The scenario: I am running three virtual machines (VMware Fusion 1.1 on a Mac Pro). All of them use exactly the same hardware playground. Each of the machines is running with a different FreeBSD installation: RELENG_5, RELENG_6 and RELENG_7. There is another virtual machine with 8-CURRENT with a slightly different setup, but all of the VMs are using two virtual processors, 512 MB RAM and a 100 GB harddisk. The RELENG_5, RELENG_7 and the CURRENT machine are working like a charm, but the RELENG_6 maching is causing trouble. Sometimes some sort of processes abort with a segmentation fault: Mar 15 23:49:30 beastie6 kernel: pid 77039 (sed), uid 0: exited on signal 11 (core dumped) Mar 16 00:12:47 beastie6 kernel: pid 35211 (conftest), uid 0: exited on signal 12 (core dumped) Mar 16 00:15:50 beastie6 kernel: pid 61400 (tr), uid 0: exited on signal 11 (core dumped) Mar 16 01:37:13 beastie6 kernel: pid 62336 (cc1), uid 0: exited on signal 11 (core dumped) Mar 16 01:51:06 beastie6 kernel: pid 41313 (sed), uid 0: exited on signal 11 (core dumped) Mar 16 02:03:10 beastie6 kernel: pid 3826 (cc1plus), uid 0: exited on signal 11 (core dumped) Mar 16 09:40:33 beastie6 kernel: pid 6094 (sed), uid 0: exited on signal 11 (core dumped) Mar 16 11:19:56 beastie6 kernel: pid 94667 (xargs), uid 0: exited on signal 11 (core dumped) Mar 16 11:20:12 beastie6 kernel: pid 97386 (sed), uid 0: exited on signal 11 (core dumped) Mar 16 11:27:49 beastie6 kernel: pid 22796 (pkg_info), uid 0: exited on signal 11 (core dumped) Mar 16 11:48:09 beastie6 kernel: pid 97969 (cat), uid 0: exited on signal 11 (core dumped) Mar 16 12:05:44 beastie6 kernel: pid 16624 (bdftopcf), uid 0: exited on signal 11 (core dumped) Mar 16 13:15:04 beastie6 kernel: pid 49750 (sed), uid 0: exited on signal 11 (core dumped) All those segmentatiopn faults occurred building some ports. None of my FreeBSD boxes uses special CFLAG settings for buildworld or ports, they just use the default settings, with the exception of CPUTYPE?=pentiumpro Initially I tried CPUTYPE?=prescott, reverting it to pentium4, pentium3 and now even to pentiumpro, but even pentiumpro doesn't solve the problem. The whone world is built using those very conservative settings. My last idea is to remove even this last "tuning" parameter CPUTYPE, but I dislike this, for it would mean to run a plain 386 box. :-( Any ideas? btw: the kernel is build using the SMP flag as the only modification. The SCHED_4BSD is used. The source tree is RELENG_6 from yesterday. Regards, Andreas Killaitis
