Wordpress lsphp

sirfpsycho

Hi, Everything was running fine on my website. But today I activated css,js minify,combine from lscache plugin. Now lsphp is using high load. I have reverted the settings and purged cache. But still lsphp is using high load. Before it was fine. How can I troubleshoot the problem?

sirfpsycho

I have checked with top -c and found that /www/wwwroot/domain.com/index.php is using high load. how to solve?

Does your website have more visits than usual?
Have you tried restarting ols

sirfpsycho

aaPanel_Jose Yes restarted ols. I have reset settings in lscache plugin and set one by one settings. Now load is fine. I have 16 cpu and 64GB RAM and load is 0.8-2cpu. But RAM usage is now 58%. And it is increasing gradually. When I click on purge all in lscache plugin, RAM uses goes down. and again increasing gradually.

sirfpsycho

when I restart ols and php after 3-4 minutes RAM uses goes down. is there any bug with ols?

aaPanel_Jose

sirfpsycho
Have you set too much cache space in lscache? Will the RAM continue to increase after closing lscache

It may be that your configuration triggers the ols bug and causes a memory leak. You can try ols for help

sirfpsycho

aaPanel_Jose I have installed lscache and deleted it but still RAM goes high. I had set child process to 100 because I can see in log it is passing 50 child process.
If I restart ols and php then RAM usages goes down after 4-5 minutes.

sirfpsycho
This may be because too many processes occupy memory.

Why don't you try the [website speed] plugin, which can cache the requested pages for you to avoid too many child processes

sirfpsycho

aaPanel_Jose I installed it but error is coming website speed supports only nginx and apache. I am using ols.

sirfpsycho

aaPanel_Jose any solution for me? I have to restart ols 3-4 times in a day to reset RAM usages.
