any core files (/var/spool/abrt)? Unluckily no, because abrtd segfaulted collecting them. Closing this bug since we haven't been able to reproduce this issue, please re-open if this issue is still present. |
Created attachment 813854 [details] "fence_virtd -F -d99" output Description of problem: hypervisor:bucek-03 <------> hypervisor:doom-driver \_virtual:bucek-03-node01 \_virtual:doom-driver-node01 physical:doom-driver I have two physical machines acting as hypervisors (bucek-03 and doom-driver) each having one virtual machine named $(hostname -s)-node01. fence_virtd is configured on both hypervisors to talk to each other using backend{} part in config file and has 'serial' as listener{}. fence_virtd segfaulted on bucek-03 after trying to off and on bucek-03-node01 from doom-driver-node01 using fence_virt. fence_virtd[31689]: segfault at 0 ip 0000003c36b3383f sp 00007f5fe341ec58 error 4 in libc-2.12.so[3c36a00000+18b000] Version-Release number of selected component (if applicable): fence-virtd-serial-0.2.3-15.el6.x86_64 How reproducible: happened once Steps to Reproduce: seed additional info. Additional info: doom-driver-node01$ fence_virt -D /dev/ttyS1 -o list bucek-03-node01 1893c3d4-77e6-4233-28ce-6b2c75d00981 on doom-driver-node01$ fence_virt -D /dev/ttyS1 -H bucek-03-node01 -o status doom-driver-node01$ fence_virt -D /dev/ttyS1 -H bucek-03-node01 -o off doom-driver-node01$ fence_virt -D /dev/ttyS1 -H bucek-03-node01 -o status doom-driver-node01$ echo $? 2 doom-driver-node01:~]$ fence_virt -D /dev/ttyS1 -o list doom-driver-node01:~]$ fence_virt -D /dev/ttyS1 -H bucek-03-node01 -o on fence_virtd segfaulted on bucek-03 Virtual machines are behind NAT. There is a lot of 'libvir: XML-RPC error : Cannot write data: Broken pipe' which might have samething to do with that. This happened only once and I have not been able to reproduce it since.
