How many files per directory do you have when you reach the limit?
I would first check that there are no fail counts in /proc/bc/resources.
Maybe one of the following are set too low in the config file:
NUMFILE="9312:9312"
DISKINODES="2000000:2200000"
Getting a real fs inside a container with bind mounts
If you are really hitting the max number of files per directory and and you can't move your files to sub directories, then you can pretty easily get a real filesystem (ext3, xfs, ...) inside the container.
You can also delegate a whole block device to a container and mount a real filesystem from that block device during boot by placing an entry into /etc/fstab inside the container. See the vzctl(8) --devices b argument. Also check /proc/filesystems inside your container to see what filesystems are available.
Put your files in sub folders.
