OpenVZ privvmpages limit
If customer got error during installing applications or in similar cases like: "unable to fork" probably it's due to privvmpages limits.
You can view the beancounters using next command from inside the vps:
cat /proc/user_beancounters
if privvmpages result equal to :
privvmpages 102486 131072 131072 131072 6701251
you can try to increase it x2 with next command
vzctl set <vmID> --privvmpages <calue>:<value> --save
For example:
vzctl set 324 --privvmpages 262144:262144 --save
Note that privvmpages and some other values can be changed using SolusVM admin CP
