[rabbitmq-discuss] [rabbitmq] /var/log/messages flooded with su: (to rabbitmq) root on none

[Narasappa, Usha]

Hi,

We use rabbitmq-c amqp client (0.2.0) to publish messages to RabbitMQ broker. The /var/log/messages file is flooded with the following:

Oct 23 05:32:29 director-1-1-a su: pam_limits(su:session): invalid line '^H' - skipped
Oct 23 05:32:44 director-1-1-a su: (to rabbitmq) root on none
Oct 23 05:32:44 director-1-1-a su: pam_limits(su:session): invalid line '^H' - skipped
Oct 23 05:32:59 director-1-1-a su: (to rabbitmq) root on none
Oct 23 05:32:59 director-1-1-a su: pam_limits(su:session): invalid line '^H' - skipped
Oct 23 05:33:14 director-1-1-a su: (to rabbitmq) root on none

It appears that root used the su command to take on the identity of "rabbitmq".
I also see that /etc/passwd file has the "rabbitmq" username which kind of proves the above theory.
It would be of great help if you could let me know what exactly is done after taking on the identity of "rabbitmq".
Basically, I am searching a way to turn off these messages so that /var/log/messages does not overgrow and lose important information.
As an additional information, logs under /var/log/rabbitmq do not have any error messages.
Any other clues/suggestions/pointers are  welcome.

Thanks,
Usha
