Out of Memeory

[mpahlevanzadeh]

I get the following text in dmesg:
Out of memory: Killed process 1802 (php) total-vm:9187292kB, anon-rss:2984740kB, file-rss:3164kB, shmem-rss:0kB, UID:33 pgtables:9460kB oom_score_adj:0

I have 12G memory, How can I solve it?

Are you using cactid service or cron? Also, what plugins?

[mpahlevanzadeh]

I use cron:
*/5 * * * * root /usr/bin/php /opt/cacti/poller.php > /dev/null 2>&1

By the way, i have the following diffrences PHP:

Why do I have /usr/bin/php and php ?

[TheWitness]

Cacti version?

[mpahlevanzadeh]

1.2.23

[TheWitness]

Get yourself on 1.2.24, and let's revisit this.

[mpahlevanzadeh]

I think it' can handle with memory_limit of php.

[TheWitness]

Most of my Cacti servers have 16GB - 32GB of memory, and for a few thousand hosts, that should be more than enough. I also support some very large installs that have over 300GB of memory for just the web servers. So, if this problem is repeatable, you need to start to trace it by running top and sorting by RSS and tracing the process taking all that memory. If you have a lot of users, you may have to decrease the memory limit to maybe 400MB. Most everything in Cacti, for smaller installs take less than that these days, especially with PHP7.4++.
