Internal server error 500 / blank page sometimes only on certain categories

[marco.azzali.76]

Hi,

I have a strange problem: only on 3 categories over 30, and only sometimes, (about 30% of page views), I get internal server error 500.
Any explanation / solution ?
I have access to log and error lof of Apache, but no trace of the error.

Thank you in advance
Marco

VM 2.6.6 on Joomla 2.5.20, PHP 5.3.28

What says the virtuemart log? You can access it within virtuemart in the tools section.

Hi Milbo,

thank you..

It's memory limit, 60MB reached. I've found it now also in the apache log.
Unfortunately probably my hosting plan wouldn't allow me to increase it..
Is there any way to reduce the consumption ?

In Apache  error log I can see lines like this:

[Mon Jun 02 03:20:03 2014] [warn] [client 157.55.39.22] mod_fcgid: stderr: PHP Fatal error:  Allowed memory siz

c_html/plugins/system/codeisgoogleanalytics/codeisgoogleanalytics.php on line 37

In Virtuemart PHP log I can see line like this :

I have multilanguage enabled but I don't really need it; disabling it would help ?

I also have URL rewriting for SEO  enabled, the default joomla one, but I can't disable it...

Once I installed AceSEF and then removed it, but the removal process for some reasons showed some errors; could this have impacted on memory usage ? (maybe some components of AceSEF are still in use ?)

P.S.: many rows like this also in apache error log:

60Mb is just too low to run VM - your not doing yourself any favours by trying to run a complex shop on a lame server  - would advise 256 if only for your customers useability
speak to your host - they are being very tight on 60Mb

[marco.azzali.76]

It should be the best in Italy.. Joomlahost by Colt Engine
I have the "medium" plan" .. In the best plan the memory limit it 96 MB as I'm reading now...

https://www.digiserv.biz/web-hosting/cpanel/entry-level/germany/

€4 a month

10GB disk - 256MB  - 24/7 support by very knowledgable engineers

€2.75 - 5GB - 192Mb

[marco.azzali.76]

Mmhhh.. sounds good.. thank you for the advice ! But I also have the dns and the mantaining of the domains there, it would be time consuming to move everything..
Moreover, Colt Engine has good support also via tickets and it's famous for reliability.
I will consider to move, but, at first, I would like to know if ther's a way to diminish the memory usage..
Does anybody have any advice ?

Recommended minimum memory_limit for Joomla 2.5 is 128Mb - there are too many reports of memory issues with less than that (even without VM being installed) and I prefer to use 256Mb although that does not give any real speed advantage, but does help on a busy site.

Re digiserv - I have no connection with them except as a extremely satisfied client

I have been in this business too many years to admit  and have had a ton of hosts and worked on sites on many many more.

I have been dis-satified for one reason or other with 95% of the hosts.
Discovered digiserv while working on a new clients site - was amazed by the speed and more amazed by the fact that it was just a normal shared cpanel host - very cheap.
Germany based at http://hetzner.de/ datacenter - one of the more expensive in Germany.

Have been with them 18 months now and are totally satisfied -- cPanel, full access to CloudLinux as in choose your own php versions and settings and all the other goodies that cPanel offer

Best is their support - the lengths they go to to find problems is amazing... I have help tickets that go on for pages as we try to sort difficult scripts and installs etc - can't praise them highly enough - not only that they are willing to change core settings etc after consultation - e.g to make Akeeba kickstart run better

The only down-side maybe for some is they are security paranoid e.g ftp over FTPES which can make it a bit clonky on some clients, enforcement of secure passwords  and agressively anti-spam - no bulk mail etc - heavy spam filtering and bouncing of non- standards complient servers etc

Even though a south African company their help centre is in the UK with actual UK support as opposed to a front for sub-asia help centres with guys called Frank who can't piece together an English sentence... 

P.S Domains no problem  - just use an addon domain in cPanel and change your current domain's nameservers to digiserv's name servers - no need to transfer anything to do with domains

[marco.azzali.76]

Thank you all for advices !
I will ask them to provide at least 128MB if I upgrade to the higher plan (that has also SSD storage), otherwise I will move.

Same here and THIS forum is running on a hetzner server!

[marco.azzali.76]

Do you mean Milbo that the problem is manifesting also in this forum's site ?
Or that you are also amazed by digiserv ?
