I'm seeing this over and over via dmesg: __ratelimit: 11 callbacks suppressed setroubleshootd[8764] general protection ip:3f8229990d sp:7ffff24ec570 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8766] general protection ip:3f8229990d sp:7fff45eddf60 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8768] general protection ip:3f8229990d sp:7ffff33353b0 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8770] general protection ip:3f8229990d sp:7fffa0fce050 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8772] general protection ip:3f8229990d sp:7fff9f1b2ca0 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8774] general protection ip:3f8229990d sp:7fff910a1120 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8776] general protection ip:3f8229990d sp:7ffff2b88c00 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8778] general protection ip:3f8229990d sp:7fffdee53ed0 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8780] general protection ip:3f8229990d sp:7fffda0360b0 error:0 in libpython2.6.so.1.0[3f82200000+169000] setroubleshootd[8786] general protection ip:3f8229990d sp:7fff2548f510 error:0 in libpython2.6.so.1.0[3f82200000+169000] The CPU is pegged at about 1.50 as setroubleshootd keeps getting respawned. This occurred after I updated to rawhide for 02-Apr-2009. Let me know if there's any other debugging info I can provide.
I'm seeing something similar on current rawhide but with slightly different symptoms, so I'm not sure if it's the same, related, or just a random coincidence. I don't see the errors in dmesg, but I do get entries in messages (extract attached) suggesting that setroubleshootd is itself getting AVC denials, and there's a lot of CPU usage. Stopping auditd breaks the cycle, and it can then be restarted without the problem immediately starting again. I suspect it may start again on the next AVC denial, but I'm not sure if there's a good way to deliberately trigger one.
Created attachment 338038 [details] Extract of /var/log/messages showing setroubleshootd failures
The AVC messages about setroubleshoot are caused by a bug in the nss package, which should be fixed in todays rawhide. The crashing of setroubleshoot is fixed by the update of todays libselinux. setroubleshoot going nuts starting and stopping should be fixed by an update to its setroubleshoot package in tomorrows rawhide. nss x86_64 3.12.2.99.3-5.fc11 rawhide 1.0 M libselinux i586 2.0.79-5.fc11 rawhide 105 k setroubleshoot-2.1.7-1.fc11
