Oracle Database Discussions

Hi All,

We get ORA-24550 error on our production app server and the server crashes.
We have tomcat as app server and we are using Oracle 10g as the the database.

I have attched the call stack trace which is recieved just be fore the crash.
There is no pattern in this and happens any time . It happened twice in last one month .

ORA-24550: signal received: [si_signo=25] [si_errno=0] [si_code=0] [si_int=0] [si_ptr=(nil)] [si_addr=0x4e0d]
