Hi guyz.. I am trying to send RT signals to the user process from kernel but the default value of queue size is 1024, which is too few for me so i tried to change the value of MAX_SIGPENDING to 8096 but that did not effected the queue overflow problem. do i need to change any other limits.. i want to change the queue size for a perticular(known PID) process. how can we do that..because the size of queue is per user,i dont want to change the value for entire system. thanx for help.. -prady -- Kernelnewbies: Help each other learn about the Linux kernel.
