Hello,

We cannot advise you to move to dedicated server just because of your domains fail often, as it might be due to some other problems like resource shortage on your server. I have checked your server and found that you have lot of failcounts in memory and other fields like numfile and numflock
---------------------------------
-bash-3.00# cat /proc/user_beancounters
Version: 2.5

numflock 9 9 500 500 333
numfile 5595 5604 40000 40000 437
---------------------------------
and we have increased the numflock and numfile values. Also it would be nice if you could upgrade RAM on server as soon as possible. Let us know if you face any issues in future.
