Description of problem: Using check_mysql against a MySQL database slave that doesn't report the `Seconds_Behind_Master' column in SHOW SLAVE STATUS will segfault if the -S switch is used. Version-Release number of selected component (if applicable): nagios-plugins-1.4.8-1 How reproducible: Always Steps to Reproduce: 1. /usr/lib{,64}/nagios/plugins/check_mysql -H 1.2.3.4 -u user -S 2. 3. Actual results: Segfault Expected results: Should display the normal MySQL statistics as well as the status of the slave thread and _optionally_ the seconds behind master, if it exists Additional info: I've created and attached a quick patch that fixes the problem for me.

I believe this has already been fixed upstream with 1.4.11. I'm requesting a release of it today, let me know if it fixes your issue. Sorry its taken so long...
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '7'. 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 7'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 7 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 please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you. 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. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 7 changed to end-of-life (EOL) status on June 13, 2008. Fedora 7 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
It seems that this bug was fixed actually.
