-## Miscellaneous
+## Duplicate Poller Entries
 
-Up to current cacti 0.8.6h, table `poller_output` may increase beyond reasonable
-size.
+If you installed Cacti from a package (RPM, DEB, etc.), the package may have
+created both a cron entry in `/etc/cron.d/cacti` and enabled the `cactid`
+systemd service. Running two pollers simultaneously causes data corruption.
 
-This is commonly due to php.ini's memory settings of 8MB default. Change this to
-at least 64 MB.
-
-To check this, run the following SQL from MySQL CLI (or phpMyAdmin or the like)
-
-```sql
-select count(*) from poller_output;
-```
-
-If the result is huge, you may get rid of those stuff by
-
-```sql
-truncate table poller_output;
-```
-
-As of current SVN code for upcoming cacti 0.9, I saw measures were taken on both
-issues (memory size, truncating poller_output).
-
-## RPM Installation
-
-Most rpm installations will setup the crontab entry now. If you've followed the
-installation instructions to the letter (which you should always do ;-) ), you
-may now have two poller running. That's not a good thing, though. Most rpm
-installations will setup cron in `/etc/cron.d/cacti`
-
-Now check all your crontab, especially `/etc/crontab` and crontab of users root
-and cactiuser. Leave only one poller entry for all of them. Personally, I've
-chosen `/etc/cron.d/cacti` to avoid problems when updating RPM's. Most often,
-you won't remember this item when updating lots of RPM's, so I felt more secure
-to put it here. And I've made some slight modifications, see
+Check for duplicate entries:
 
 ```sh
-shell> vi /etc/cron.d/cacti
-```
-
-```ini
-*/5 * * * *     cactiuser       /usr/bin/php -q /var/www/html/cacti/poller.php > /var/local/log/poller.log 2>&1
+systemctl status cactid
+cat /etc/cron.d/cacti
+cat /etc/crontab
+crontab -l -u cactiuser 2>/dev/null
+crontab -l -u root 2>/dev/null
 ```
 
-This will produce a file `/var/local/log/poller.log`, which includes some
-additional information from each poller's run, such as RRDtool errors. It
-occupies only some few bytes and will be overwritten each time.
-
-If you're using the crontab of user "cactiuser" instead, this will look like
+The recommended approach is to use the `cactid` systemd service and remove any
+cron-based poller entries:
 
 ```sh
-shell> crontab -e -u cactiuser
+systemctl enable --now cactid
+# Then remove or comment out any poller.php line in /etc/cron.d/cacti
 ```
 
+If you need to keep cron-based polling, disable the service and leave a single
+cron entry:
+
 ```ini
-*/5 * * * *     /usr/bin/php -q /var/www/html/cacti/poller.php > /var/local/log/poller.log 2>&1
+*/5 * * * *  cactiuser  /usr/bin/php -q /var/www/html/cacti/poller.php > /dev/null 2>&1
 ```
 
+Replace `cactiuser` with the user your web server runs as (e.g. `www-data` on
+Debian/Ubuntu, `apache` on RHEL-compatible systems).
