Got invalid response from API request - once again (no replies)

Hey there,
I did search, I swear, but I can't get some useful Infos:

I have an VPS for my Piwik-Instance, over 20 Websites will be tracket, this will grow up. But there are just 4 or 6 Websites who have more than 10 Visits a day, most are really little pages.


The biggest Page got over 1.000 (thousand) visists a day, and this seems to be an little problem, here my archive.log

I think the Time is 2 hours offset to me, currently its short before 11 AM. (Germany)

This error appears everytime. Just for this Page. Error-Log of this vhost ist empty. Just the apache-error-log says

[Thu Sep 19 10:46:23 2013] [notice] child pid 30486 exit signal Segmentation fault (11)
[Thu Sep 19 10:47:32 2013] [notice] child pid 30484 exit signal Segmentation fault (11)

Memory-Limit is 1G, should be fine, or not?

This page had around 200.000 Visitors this year (till now) manualy calculated over the months.


Anyone got ideas what I can do?


Regards and thanks for any help,
Oli
