@hereabdulla care to explain?

mean?

@hereabdulla you just posted the code of bench start, but didnt explain any errors or any symptoms …

oh sorry I installed frappe and erpnext manually after completing all steps when I run bench start it shows the below error

redis_socketio.1 started (pid=6292)
15:15:23 redis_socketio.1 | 6298:M 22 Apr 15:15:23.283 # You requested maxclients of 10000 requiring at least 10032 max file descriptors.
15:15:23 redis_socketio.1 | 6298:M 22 Apr 15:15:23.283 # Redis can't set maximum open files to 10032 because of OS error: Operation not permitted.
15:15:23 redis_socketio.1 | 6298:M 22 Apr 15:15:23.283 # Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.

@hereabdulla you have two main errors:

15:15:23 redis_socketio.1 | 6298:M 22 Apr 15:15:23.283 # You requested maxclients of 10000 requiring at least 10032 max file descriptors.

and

15:15:23 redis_socketio.1 | 6298:M 22 Apr 15:15:23.283 # Creating Server TCP listening socket *:12000: bind: Address already in use

and both are in the same section : redis_socketio

i dont have much knowledge about redis but try to read the configuration on your server…
:12000: bind: Address already in use
