Hi

language:c
OS:redflag


In my multithread server-client program I have to run more than 1000 threads. But when I try to run more than 300 threads following errors are occured.

I/O error : Too many open files
I/O warning : failed to load external entity /home/naveen/TEST/sysinfo.txt"

In my program each and every thread has to read sysinfo.txt file.

how to get rid from this.

can we use 'sysctl'? how can we use this command.

I have changed file-max from 104176 to 214176.. I have rebooted.. but still I am getting same error..


pls help me!!!!

thanks in advance..

Now that you use threads instead of processes, why don't you just open the file once? You can share the file descriptor between threads and use locks to control the access.
