Description of problem: fence_xvm aborts after logging: *** buffer overflow detected ***: fence_xvm terminated Version-Release number of selected component (if applicable): fence-virt-0.3.0-2.fc17.x86_64 How reproducible: rare Steps to Reproduce: Unknown, pops up occasionally when running pacemaker's CTS test suite. Possibly running multiple instances at the same time? Interestingly, tcp_wait_connect() is being called with lfd=-1 which looks suspicious: 337 fd = tcp_wait_connect(lfd, args->retr_time); Actual results: Boom Expected results: No boom Additional info: Core was generated by `fence_xvm'.

Oh, there was one more log message that I missed the first time which seems to back up my "running multiple instances at the same time" theory: Failed to listen: Address already in use Looks like we're just not bailing out properly.
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Can we not get this fixed?
Sorry, forgot to add fence-virt on fedora to my bugzilla query. This should be fixed in upstream commit 04710b40794fb31e9cd70c4a205decf6b40206fd I'll do a new build for Fedora shortly.
