Problems after migrating to VPS with DA

[nakkie040]

Hi All,

First of all, my name is Michiel and im fairly new to DirectAdmin so my troubleshooting skills are not that good.

The problem
since the migration to a new VPS our site is not functioning properly and i cant pinpoint where the issues are comming from. i did the migration myself with the steps found on this page. the server specs are: 1 dual core processor 512mb memory and 256 swap memory. the site seems to load fine but when browsing to other pages it becomes unresponsive, this also happens on the wp-admin page. when i reboot the VPS the site runs ok for about 10 minutes but after that becomes unresponsive again.
i have change the max script runtime to 60 and the script memory to 64mb in php.ini but that doesnt show any results.

i hope that someone here can point me in the right direction.

thanks in advance!!

Michiel

the error we are receiving is :
No data received
ERR_EMPTY_RESPONSE
Unable to load the webpage because the server sent no data.

First of all, you should have twice as much swapspace as the RAM you have, although your server most likely dies anyway as soon as it starts swapping.
The minimum requirements for running da and it's services is 1GB. Depending on your sites this may be enough... or not...

If the site runs ok after a reboot but slows down after that you might try adding more ram to the vps. With 512 MB you run out of ram quickly when more users visit the sites, or bots start retrieving pages. Besides that, it often takes a few minutes for mysql to fill it's memory buffers.

Login to you vps and run tools like top, free etc to see if your system starts swapping. If so, add ram.

LOG files error logs saying something?

DISK and SwapMEM on SSD ?
Uh who was selling/advice you this vps in nederland ? no not answer me this.

If you didn't get it by advice, did you get it to try out the smallest config first by yourself, then i understand

All PAths exact the same as before, cache , sessions, temps, cleaned old cache and tmps.
