Server keeps throwing 500 error and server load is always above 1.00 Please Help.

[rushaboswal.rdx]

Hello my website was running fine for around 2 years and suddenly this happened.

It keeps throwing 500 errors and server load is always around 1.00-1.10. 
When contacted hosting they said too many proccess are running . But im unable to pinpoint the exact issue from logs or any other help topics.

Can somebody please help.

[rushaboswal.rdx]

Also when checked MYSQL Monitor , the system CPU Usage is always 100% What could be the issue ? 

[rushaboswal.rdx]

Any help ?

Hi, 

A vcouple of issues spotted : 

 

1. Lower your PHP from 7.4 to 7.2 - Ps .1.5.2 doesn't support the latest PHP ==> 

https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/

2. Ask your host to activate either PHP x-ray or new relic on the server. 

3. Ask your host to activate for 1 H the server slow query logs . 

What they said it equals to zero! It would have been the same if I would have said about their host that s...s, without getting proper background information. 

I presume that lowering the PHP will solve most of the issues. 

Keep us posted. 

Cheers, 

Leo

The lowest my server provides is 7.3 they are the least helpfull in activating logs too. I think i might just migrate to a VPS Hosting with root access.

We had the same issue weeks ago with a  different client, and after almost 2 weeks of struggling we moved the site to a different server, and case was closed, as everything started working properly with the lower PHP. 

Of course the best option to keep track with Ps newest version, however before holiday season, I suppose that's not an option. 

One last question : under performance is the cache set for file or MySQL ? 

cheers,

Its set to files.

i hope thats the right settings.

thanks for all the help 😇

[Prestachamps]

The files setting is fine (I made only a connection between your high MySQL usage). 

I'm not sure what the next should be : 

1. start setting the Php 7.3 

2. enable profiling for your IP only.

3. under your site, each request has a TTFB of over 30 seconds. What I noticed is that the modules/appagebuilder is getting a 403 (forbiden), as well the images ===> 

are you sure that the folder rights are set properly (ask your server to use a ch Mod ). 

Important : go to the SEO and URL section and press save on that page to regenerate the htaccess.

1) switched back to 7.3

2) how can i do that i can enable profiling but not for specific ip

3) permissions are correct (755)

4) .htaccess done

still no improvement 😑

 

[Prestachamps]

Can you make a quick test pls: just add a hello.php in the public html, and add teh following into it : 

<html> <head> <title>PHP Test</title> </head> <body> <?php echo '<p>Hello World</p>'; ?> </body> </html>

Keep me posted (if this is slow - the issue lies on the server)

Can you check by disable your thirdparty modules from Performance tab. and check if you are running any module which call the db query , which may made this kind of issue. You also need to clear the database visitory connection .Which will smaller the db size.

Hope this will give you a idea

 

thank you

I did try disabling it but no luck.

Also the guest tables have already been cleared.

ps_layered_price_index is the biggest table now with around 163,326.

Yes. Vps is next logical step after shared hosting.  Shared typically throttles connections and other processes, disables mod_expires is another popular one.  If they did not do this then you would have a vps.

Look for entry level vps with plesk control panel.  What is your country and budget for hosting your business?  Who is your current hosting company?  

Tip, ovh has vps with nvme ssd hardware, makes shop very fast.

Im currently on bigrock which has 

6 CPU cores and 6 Gb ram. Currently costing around 10$ a month. Im from india and upto 30$ is fine.

Also im more familiar with cpanel. Is plesk better than cpanel?
Also i heard Ngink is faster than apache, is that true?

Look to upgrade from shared with existing hosting company but I'm sure India has many hosting companies so shop around.

Plesk is better option than cpanel IMHO.  More tools.  Ngnix can benefit as you can then use php fpm.

This is what i found out when i ran mysql Tuner. What could be causing this?

[ZHSoft]

Please keep disabling third-party modules until there is no 500, and find out which module caused the 500 error.

Its not a permanent 500. 
it comes and goes, and whenever its there i mostly have too many connections in mysql (Max i can have is 151) but i dont have those many visitors at a time( This many i may have in an hour)

[rushaboswal.rdx]

Just found out i cannot switch to VPS as the bandwith they provide is 2TB, While Network traffic since startup is 9.4 TiB for my sql just for 18 days, (Which according to support team will be counted in total bandwith).

I ran debug profiler and attaching results , i also now using cloudflare to deter away bots. 

Debug profiler results attached. 

[rushaboswal.rdx]

Switched to VPS finally.

But the load times are a bit higher than that on shared hosting.
Runnin PHP as Dedicated FPM application served by nginx. 
Here is the Information from prestashop information page. any help ? @El Patron ?

[PrestaHeroes USA]

Hi you can pm me with your email and I will have Daryl take a look for you.  It's not possible to help always without access.  We do pro Bono work so there would be no charge.

On the Firefox it loads quite fast. As for me. 1-1,5sec on front page. On product page is little slow, probably because zoom option. You could try also try some lazy load image module to speed it up.

The problem is on categories page where products images load slow . Can you check that too?

Little bit slower but not that bad. Around 1,2 sec. Lazy load module could help in that, i think.

You are saying whole page loads in 1-2 seconds? Did you try multiple pages in same categories? Like page 1-2-3-4-5-6. For me here it takes 1-2 seconds for EACH IMAGE.

That is correct. Its load quite fast for me. Maybe try other internet browser, clear browser cache. Test your page on PageSpeed Insights and read the results https://pagespeed.web.dev , it doesn't show any big issues with loading time.

Ok thanks. Can there be an ISP cache issue?

You could ask your hosting provider, so they can look into it.

i checked shop from S. Amerca, mobile loaded plenty fast.

it's probably your work  connection looool

as mentioned hosting upgrades solve 99% of all performance issues...
