PING command giving error , "Error: Resource temporarily unavailable" after running process for a few hours.

[shivangi-12]

I am using a daemon process which creates multiple concurrent connections to Redis. I am using [redisConnectWithTimeout] function to connect with Redis with a connect timeout.After running the process for a few hours , the PING command gives this error , "Error: Resource temporarily unavailable" which suggests there is some issue with Redis DB , so we try to reestablish the connection but we get this error everytime. Furthermore , redisFree is giving core dump after we try to free the context just after this error.

reply = redisCommand(*c,"PING");
if(reply == NULL)
{
printf("command failed");
printf("Error: %s\n", (*c)->errstr);
redisFree (*c); -- This command is giving us core dump

  // connecting redis back again 

}

There's not really enough to go on to help you diagnose the issue.

Can you provide a minimal working example that can replicate the problem you're seeing?

As for the core dump, I would suggest running your program under a debugger or via a tool like valgrind to tell you exactly why the crash is occurring. It could be in hiredis or somewhere else in the program.

so we try to reestablish the connection

How do you re-establish the connection?
