Siege cannot perform load testing for more than 255 tests

My Siege version is:

4.0.2 and ubuntu : 16.04
Siege is installed in cd ./.linuxbrew/Cellar/siege/4.0.2/etc/

I couldn’t make a load test more than 255 and getting a warning message in below you can see.

 siege -c1000 -t5m  http://192.168.1.11:8080/



 WARNING: The number of users is capped at 255.  To increase this
         limit, search your .siegerc file for 'limit' and change
         its value. Make sure you read the instructions there...
================================================================
** SIEGE 4.0.2
** Preparing 255 concurrent users for battle.
The server is now under siege...

so on ctrl+z

Then I edited siegerc file:

sudo vim siegerc

verbose = true
color = on
quiet = false
show-logfile = true
logging = false
limit = 3000
protocol = HTTP/1.1
chunked = true
cache = false
concurrent = 3000
connection = close

Even after restarting my machine, still getting the same warning message and loading only my 255 tests.
What should I do, If I want to run more than that?
