    After running in a fairly stable way for months, we’ve upgraded to MONyog 6.5 before Christmas, and had the process die 3 times in 4 weeks. Each time the process logged a segmentation fault. Running on Centos 6.5:


    [root@(server) MONyog]# cat /etc/centos-release 
    CentOS release 6.5 (Final)
    [root@(server)  MONyog]# uname -a
    Linux (server.fqdn) 2.6.32-431.3.1.el6.x86_64 #1 SMP Fri Jan 3 21:39:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
    [root@(server) MONyog]# rpm -qa | grep MONyog
    MONyog-6.5.0-0.x86_64

    The error was logged 3 minutes after a failed call to the AWS API to get logs from an RDS server, and a curl timeout seems to be involved in the crime. It had been logging a similar failure every 5 minutes; something about that RDS DB isn’t happy – but that shouldn’t be crashing my entire database monitoring application!

    We’re running the enterprise version, if that’s relevant. I’ll try to hunt down the customer login details and send over the core dump, but wanted to post something public so anyone else with the same issue can see it’s not a one-off!

    Hello,

     

    This issue related to the curl library crash while resolving too many hostnames was fixed in our latest release MONyog-6.51. You can go ahead and upgrade and the issue will be fixed.

     

    Regards,

    Pankaj

    Team MONyog.
