Answer 1

I had a similar error, but I obtained the si_signo=11 (Invalid memory reference according to previous comment), in my case I was working on Red Hat 6.5 and my Oracle DB was in a different server, the problem was local to my Red Hat server, here the error:

ORA-24550: signal received: [si_signo=11] [si_errno=0] [si_code=1] [si_int=1147687784] [si_ptr=0x7f8f44685368] [si_addr=0x7f8f1c001000]

In my case the fix was very simple, I had a stack size limited amount, temporary solution was to change it to unlimited

$ ulimit -s unlimited

Then I retried to launch my application, the problem was gone. This solution, indeed, made me understand I had to set a higher value for the stack size index, please consider increasing the value but not using unlimited because it's not a good practice, it might take down the server or create performance issues.
