I've created a generic service checking script, which I'm specifying in lvs.cf's 'send_program' config parameter. script is attached to this post. see that for how it works with the symlinks described below. I create symlinks to the script for every service I want to check, with their name containing the port to hit, as in: /sbin/lvs-<port>.sh so the symlink name to check ssh availability, for instance, is: /sbin/lvs-22.sh The script works fine, and returns the first contiguous block of [[:alnum:]] text data from the connection attempt for use with the expect line of lvs.cf. The problem is, when nanny is spawned by pulse, all of the nanny processes segfault. > Nov 13 14:40:44 kop-sds-dir-01 lvs[17740]: create_monitor for ssh_access/kop-sds-01 running as pid 17749 > Nov 13 14:40:44 kop-sds-dir-01 nanny[17749]: making 10.32.12.11:22 available > Nov 13 14:40:44 kop-sds-dir-01 kernel: nanny[17749]: segfault at 000000000000006c rip 000000335e570810 rsp 0000007fbfffe978 error 4 this occurs almost instantly for every nanny process. Can anyone venture a guess as to what is happening? see my lvs.cf here: <A HREF="http://nanny-error.pastebin.com/m592f7911">http://nanny-error.pastebin.com/m592f7911</A> -- Regards, -C </BODY> </HTML>
