[CPANEL-26179] Starting Spamd errors out with The system failed to execute the system call setrlimit

/etc/redhat-release:CentOS release 6.10 (Final) /usr/local/cpanel/version:11.78.0.16 /var/cpanel/envtype:virtuozzo CPANEL=release I recently upgraded MySql from 5.5 to 5.6. I had some issues with roundcube displaying emails in the inbox. Restarting exim seemed to take care of things, but now I get this strange message when it tries to start spamassassin. I thought that maybe reinstalling spamassassin would solve the problem, but it hasn't. I saw the following thread on the forums and checked the file, but mine doesn't have any uncommented lines in it: Full error code below.

Hello @pmcgilli I saw a case get opened for this issue today and realized you'd opened a ticket. Thank you for doing that. It looks like some older kernels are not able to recognize the setrlimit values used for spamassassin. We've opened an internal case CPANEL-26179 setrlimit option RLIMIT_RTTIME not available on older kernel <2.6.25, causing spamd to not start Now looking at the information available I can say two things: 1. Updating the kernel should resolve the issue as 2.6.25 and after the RLIMIT_RTTIME variable is supported: setrlimit(2): get/set resource limits - Linux man page "RLIMIT_RTTIME (Since Linux 2.6.25) 2. Because of the age of the kernel I cannot guarantee this issue will be resolved. The best solution at this point will be to update the kernel version at the very least to a version which supports this. Thanks!

Hello, To follow-up, CPANEL-26179 was marked as by-design because Spamd starts successfully and correctly reports the warning message stemming from the use of an outdated kernel. Upgrading the kernel is the best course of action to address the warning message. Thank you.
