$ ulimit -a
Example of output:core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) 805696
pending signals (-i) 1024
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8

The above output clearly stat that you can create file size upto 805MB limit.data seg size (kbytes, -d) unlimited

To change this limit or if you do not wish to have a limit you can edit your /etc/security/limits.conf file (login as the root):
# vi /etc/security/limits.conf
Look for your username and fsize parameter.
Delete this line or set new parameter.
For example consider following entry where I am setting new file size limit to 1 GB:
peter hard fsize 1024000
If you wish to setup limit for all users, use * on place of username like this (5GB limit):
* hard fsize 5000000
If you don't want to apply any limits, just delete or comment entry for your username from this file.
Save the changes. Log out and log back in for the changes to take effect.
Now your limit is 1GB file size. If you do not want any limit remove fsize from /etc/security/limits.conf.
