Comment: privileged option of process.max-file-descriptor had reached to 2.15G descriptors. But, no privileged option had been set to it. WORKAROUND:
Set privileged option to a value as an example below: # projmod -s -K "process.max-file-descriptor=(basic,4096,deny),(privileged,65536,deny)" 'user.oracle' After setting, check as below: $ prctl -n process.max-file-descriptor -i process $$

racgimon could not close file descriptors. It repeats to close different file descriptors which are incremented 1 in each subsequent close() system call.
close() system calls return EBADF, which is The fildes argument is not a valid file descriptor.
