How to change Android max file open limit per user/process

[Din Assegaf]

I try to do stop; and start; again android but stuck at too many open files error,


X00TD:/# cat /proc/self/limits                                      

Limit                     Soft Limit           Hard Limit           Units     

Max processes             10077                10077                processes 

Max open files            1024                 4096                 files     

1|X00TD:/# ulimit -a

...
-n: nofiles(descriptors)  1024

I want to try to modify android kernel config/settings, source code too if possible, but this config is not exist : 

X00TD:/ # ls /system/etc/security/limits.conf                        

ls: /system/etc/security/limits.conf: No such file or directory

1|X00TD:/ # ls /etc/security/limits.conf                             

ls: /etc/security/limits.conf: No such file or directory

how to change the limit 1024 of that ?

Hi,

You could try to use init.rc  setrlimit  command

https://android.googlesource.com/platform/system/core/+/master/init/README.md

Maybe there are parameters which will allow to change that limit.

I was able to modify NICE parameter to run my process as realtime

Example:

"[Set Resource Limit]" # set RLIMIT_NICE to allow priorities from 19 to -20 

 setrlimit 13 40 40
