ISPconfig on Debian 32-bit RAM issue

Hi, I have ISPconfig on Debian Squeeze 32-bit. Because it was installed on 32-bit vmware machine. Now I have moved to 64-bit vmware machine. It is possible to change kernel on debian to map more RAM?

Or can I do some settings to have system less RAM hungry? Because when system start use SWAP than it is very slow.

Thanks a lot for advice!

 

I found this post: http://www.debianadmin.com/howto-use-more-than-4-gb-ram-on-debian-etch.html

Any one try something like that? If I change kernel will it do some 32/64 issue to Ispconfig and package for hosting?

 

You can solve this issue easily using a 32 bit kernel with PAE support ( debian and ubuntu have it)

Switching from 32 to 64 isn't a good idea... asked many times.

 

So you say I need to know my if HW support PAE and then change kernel to bigmem?

 

Ok, I try now on my test machine Debian Squeeze on vmware.

Code:

# apt-get remove linux-image-2.6-686
# apt-get install linux-image-2.6-686-bigmem

After reboot system have 5,5GB.... So it works. My question is if there si some issue? I mean Issue with stop working hosting services on ISPconfig? Or it is save to use?


UPDATE: I Think I dont need to remove linux-image-2.6-686 - Just install linux-image-2.6-686-bigmem will be anought....
