Boost & DSStats Plugins

msw1970 · Post by **msw1970** » Mon May 10, 2010 5:32 am

Hi

I've got a situation with Cacti on RHEL5 whereby I'm continually running out of memory about every 9 days.

After a restart of the server on 6th May, I've noticed the following when doing a ps -ef | grep cacti

It appears that the poller_boost.php, poller_dsstats.php and check-uptime.php processes are not terminating correctly and more are being initiated each day thus using up more memory each time.

Start timestamp.
There is not only boost & dsstats but uptime also. It is very interesting in case of boost since it uses file locking mechanism. Do you have that lock file set correctly up?

I believe the lock file is set correctly....

The path to lock file in settings is /tmp/cacti-boost.lockf
