Same thing happening on hetzner ex4 when no clients or load. 16Gbram 750Hdd 4x i72600k, so that is
not about hardware....
Any advice depended to your server Specifications and your condition
I dont underestand your problem and i dont know you have what server (or vps )
in first post you wrote both of old and new server (or vps) have a 2 Gb ram and in next post you wrote have a backup file over 4 Gb
Moving all data from KloxoMR@Centos5.9 to KloxoMR@Centos6.4.
I have done this at least 4 times, but never with different OS so i guess that is problem. These are steps:
1. backup reseller account on old server
2. make same acount on new server
3. transfer backup file to correct place (/home/kloxo/client/USERNAME/__backup)
4. start restore on new server: step 1 and 2 (selecting and confirming) are ok, but when final step run it just extract all to /temp and stops
Like i seed this is done correctly in past so there is something wrong with backup/restore in new KloxoMR or something about OS.

and in last post you wrote , you have a very heavy ang high server Specifications with 16 Gig ram
Same thing happening on hetzner ex4 when no clients or load. 16Gbram 750Hdd 4x i72600k, so that is not about hardware....
Anay way If you have a problem in restore or backup for big volume of backup file and if you want solve it , you can doing these advice
1- if you have a normal or weak vps , you shoud set /tmp dir volume at least 3X of bigger backup file and you shoud not restore for big backup file , Together
2- if you have a very power server Specifications (i7 cpu and 16 Gig ram) and you will restore all big backup file Together at once , you shoud set /tmp dir volume at least 3x of total volume of all backup file
for calculate volume of flle and set /tmp dir , please condisered this advice too
Restore will be unzip file to /tmp. So we need space zip file, temp files and real extract files.
Certain server make a quota for /tmp.
good luck
