Description of problem: I'm attempting to get debug reports from abrt itself. This triggers an selinux warning. abrt-analyze-c is currently crashing with a segfault repeatedly. I'm attempting to get a report from this to report a bug in abrt itself. It's doing this when Python segfaults (c segfault, not python backtrace), which I can trigger reliably by running gnome-music (bz # 1635152) Basically Python segfault: Oct 17 11:50:21 sieve-deschouwer-co-za abrt-hook-ccpp[32427]: Process 32382 (python3.7) of user 1000 killed by SIGSEGV - dumping core Oct 17 11:50:22 sieve-deschouwer-co-za abrt-hook-ccpp[32428]: Can't generate core backtrace: dwfl_getthread_frames failed: No DWARF information found Oct 17 11:50:22 sieve-deschouwer-co-za abrt-hook-ccpp[32427]: Core backtrace generator exited with error 1 triggers abrt segfault: Oct 17 11:47:01 sieve-deschouwer-co-za kernel: abrt-action-ana[32174]: segfault at 20 ip 000055b6c04db953 sp 00007ffd4ee50560 error 4 in abrt-action-analyze-c[55b6c04db000+1000] Oct 17 11:47:01 sieve-deschouwer-co-za kernel: Code: e8 a2 f9 ff ff 4d 85 e4 74 38 4c 89 e7 e8 65 fa ff ff 48 89 c5 48 85 c0 0f 84 cb 00 00 00 48 89 ef e8 41 fb ff ff 48 8b 45 10 <48> 8b 50 20 48 85 d2 74 0f 48 8d 35 63 07 00 00 48 89 df e8 05 fb Oct 17 11:47:01 sieve-deschouwer-co-za abrt-hook-ccpp[32176]: Process 32174 (abrt-action-analyze-c) of user 0 killed by SIGSEGV - dumping core Oct 17 11:47:01 sieve-deschouwer-co-za abrt-server[32143]: /bin/sh: line 56: 32174 Segmentation fault (core dumped) abrt-action-analyze-c Oct 17 11:47:01 sieve-deschouwer-co-za abrt-server[32143]: 'post-create' on '/var/spool/abrt/ccpp-2018-10-17-11:46:50-32076' exited with 139 Oct 17 11:47:01 sieve-deschouwer-co-za abrt-server[32143]: Deleting problem directory '/var/spool/abrt/ccpp-2018-10-17-11:46:50-32076' Oct 17 11:47:01 sieve-deschouwer-co-za abrt-server[32143]: Lock file '.lock' was locked by process 32174, but it crashed? SELinux is preventing abrt-hook-ccpp from using the 'sys_resource' capabilities. ***** Plugin sys_resource (91.4 confidence) suggests ********************** If you do not want processes to require capabilities to use up all the system resources on your system; Then you need to diagnose why your system is running out of system resources and fix the problem. According to /usr/include/linux/capability.h, sys_resource is required to: /* Override resource limits. Set resource limits. */ /* Override quota limits. */ /* Override reserved space on ext2 filesystem */ /* Modify data journaling mode on ext3 filesystem (uses journaling resources) */ /* NOTE: ext2 honors fsuid when checking for resource overrides, so you can override using fsuid too */ /* Override size restrictions on IPC message queues */ /* Allow more than 64hz interrupts from the real-time clock */ /* Override max number of consoles on console allocation */ /* Override max number of keymaps */ Do fix the cause of the SYS_RESOURCE on your system. ***** Plugin catchall (9.59 confidence) suggests ************************** If you believe that abrt-hook-ccpp should have the sys_resource capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

This is related to debugging some process. Please create local policy module with fixes.
