Description of problem: Can not determine why Folding@Home program seg faults on these kernels sig 11. everything is the same from fc7 kernel 3194 Seperate user for fah fah dir is on vg-lv of FC6 system and is monuted under the f7 fah mountpoint i.g. mount /dev/mapper/vg21-lv06home /home/fahuser/fahmnt at famnt cd down cd fah /.fahprgramnae.exe the execmem and execstk selinux booleans are on by default in f7 (shock) in fc6 the are set and reminder setroubleshoot pops up if they are not. With the newer f8 kernels no setroubleshoot alert, no audit messages no messages pam shows fahprogm abnorm abend seg 11 Version-Release number of selected component (if applicable): f7 with a few updates (using f7 kernel 3194 or (f8 kernel ) How reproducible: everytime Steps to Reproduce: 1. Install f8 kernel and bootup start fah sig 11 2. 3. Actual results: Expected results: Additional info: Darwin
Signal 11 can be caused by bad memory, overheating CPU, inadequate power supply and a long list of other reasons. Are you sure the hardware is 100% OK? Do any other programs cause a problem? Has memtest86 been run on this hardware?
This bug can be closed. With the high summer temps and the Virtual-Box running several systems, I was able to pin point the problem a cpu heat (mainly when the FAH is using the FPU @ 100% for a few hours VS> the VB using normal CPU @ irregular intervals avg. 84%.) I also think the 23 kernel is way better than any since 18. :) Thanks, Darwin
