  • 1.  zD&T 10.0.1 ULIMIT -c

    Posted Wed August 02, 2017 10:13 AM

    Installed zD&T 10.0.1 on a RHEL VM but get a bad check on ULIMIT -c. Here's the bash message generated during sign on to the VM: ulimit: core file size: cannot modify limit: Operation not permitted.

    z1090instcheck message is REDHAT ulimit -c is not set to unlimited : = 0      BAD.

    Can zD&T / zPDT still function with this, or will my SYSADMINS have to fix the VM to allow unlimited?  

     

    So a little more investigation suggests VM ADMINS do not want users to be able to generate unlimited core dumps. So, I guess there is no impact to zD&T unless a core dump is suppressed but needed for analysis. Perhaps the VM traps the issue using another process.

    If my assumption is wrong and ulimit -c  not set will prevent zD&T from functioning correctly, please respond.

    Thanks.

    Hi John, your guess is correct, zD&T can work, but eventually you will reach the limit to opened files very quickly and  may face some issue, not only for core dumps. 

    If you have the chance, set up this recommended value. Since zD&T runs in exclusive machines (or VMs), it will not impact any other service.

    The number of opened files will be a concern. I'll talk with our VM ADMINS and management to have it set to unlimited.

    Thanks.
