Again: massive server overload with J 3.9.1
« on: December 03, 2018, 14:23:40 pm »
Hi all,

as stated in this thread: http://forum.virtuemart.net/index.php?topic=141342.new;topicseen#new there was a massive server overload with J 3.8.13. As GJC Web Design proposed, I enabled the 404 error handling in VM - and this helped. Before I start clicking and enabling/disabling around: Now we have again a really massive server overload since the update to J 3.9.1. Is there another fix for that problem? Or do I simply have to ... disable the error handling again?

Thanks in advance for your precious hints,

Martin

You don't say which VM version, but the 404 issue was fixed for com_virtuemart.3.4.3.9989  - http://dev.virtuemart.net/projects/virtuemart/files

Hi jenkinhill,

thanks for your quick reply! Actually, I use 3.4.2 and I cannot see any update hint. Is it a release candidate or do I simply have to download the files you linked to and upload them - without destroying the current shop?

Sorry for my hesitating with updating ... but I'm rather careful as this shop is quite big...

Kind regards
Martin

As with all updates, of Joomla as well as extensions, you should test on a copy of the live site first before updating the live site itself.  You won't lose any data etc when you update. 3.4.3.9989 is officially a beta, but has a lot of bug fixes, and is the version I use.

Hi jenkinhill,

after having updated according to your beta version, the server is even more overloaded (see attachments). We really are at the end of our knowledge. The server is nearly breaking down...

Every hint appreciated.

Kind regards

When i check your graphics, you have more traffic as before.
Have you check if this is not some hack attempt and have nothing todo with Virtuemart ?

We actually are subscribed to SiteGuarding to protect the site. They usually do their job very good.

The thing is, that the first series of overload had to do with the 404-error-handling which we activated according to a hint on this forum. The new overload started when updating Joomla to 3.9.1. And now, after having updated VM, it seems even more loaded...

What information or screenshots can I provide you?

I'd look at the raw access logs to see if there is a clue there. It is a good way to check for hacking attempts.

Doesn't look like. Just the usual ones, like this:

2018-12-04T14:14:33+00:00   INFO 91.210.147.71   joomlafailure   Benutzername und Passwort falsch oder das Benutzerkonto existiert noch nicht!

But that's about a hundred or so per day.

But what makes me a little wondering is the mass of Google requests according to the stat (attached). There are some 1314186 hits in december just by Google.

You may want to turn Virtuemart 404 handling off

Dodgy urls are rewarded by a VM shop page which drains resources - some people want this - I prefer a true redirect or nothing!

Another thing you can do is to return a very unhelpful and small 403 message using .htaccess



Code: [Select]
ErrorDocument 403 "Forbidden"
If you add this at the end of .htaccess - then you only give over a few bites to people using crap urls instead of rewarding them with a 404 page and bandwidth.

Did you turn off VM error handling? - if you leave it on, some bad shop requests will get redirected to a VM shop page
