Hi @iamfromsky ,   Thanks for the detailed information with stack trace. I did some research and think this may fit an old bug we had in the agent code which is triggering this memcpy. Ultimately the problem is due to one log file which happens to have some insanely long log lines. Some questions for you: What services are installed on this host? Have you turned on any debugging on any service? Suggestion for you to see if you are hit by this issue: On the problematic host, stop CM agent Clear out all the log files under /var/log directory which are managed by CM Start CM agent Then check if the issue is solved Note: Before you clear the logs out, please make a backup in case you need to do a RCA to see which service is causing the long line.   If the issue still exists after doing above, then you should try to collect below information for further analysis: 1) collect top/pstack for the agent process 2) Run "SIGQUIT" on the agent PID, e.g.# kill -SIGQUIT <pid> 3) Provide the agent logs. 4) Provide the output of the command "netstat -anp"   Thanks and hope this helps, Li ...

Hi @iamfromsky ,   Could you please share your CDH/CM version? As you mentioned, I would definitely check the resources (CPU, memory, free spaces, /var/log/messages, network etc) on that host. Also, check service monitor host and service monitor logs and see if that reveals anything.    Thanks, Li ... View more

Hi @teolux ,   I am following up to see if you will be installing chronyd? Hope you have resolved the issue already.   Thanks, Li ... View more

Hi @m4x1m1li4n ,   Looks like you used custom location. You may want to take a look at the location:  /opt/cloudera/CMCA and see if there are some data inside. Try to move those files to different location and see if that helps.   Thanks, Li ... View more

Hi @teolux ,   You may want to read this thread: https://community.cloudera.com/t5/Support-Questions/Should-Cloudera-NTP-use-Chrony-or-NTPD/td-p/55986   Basically Either NTP or Chrony can be used.   Thanks, Li ... View more

Hi @teolux ,   Do you have chronyd running on this host? Cloudera Manager agent will run the following command to determine if chronyd is running:   # pidof chronyd   If there is a chronyd process running, then the above command will return the PID of that process. Please run the "pidof chronyd" command and see what the output is. If there is a PID returned, use "ps aux | grep <pid>" to find out what that process actually is.   If you do not want to use chronyd, then disable that. Also restart Cloudera manager agent afterwards.   Thanks and hope this helps, Li ... View more
