Symptoms

The following messages in the alert log file and thereafter the instance crashed.

ORA-00603: ORACLE server session terminated by fatal error
ORA-27504: IPC error creating OSD context
ORA-27300: OS system dependent operation:socket failed with status: 11
ORA-27301: OS failure message: Resource temporarily unavailable
ORA-27302: failure occurred at: sskgxpcre1

Cause

This error means that there was an socket failure happened at the OS level while we try to communicate with
the remote node.

This issue can be caused if the MAX_ASYNC_PORTS has low value as it required to create a socket for a
useof the private interconnect when required.

MAX_ASYNC_PORTS specifies the system-wide maximum number of ports to the asynchronous disk I/O driver
that processes can have open at any given time. The default value for this parameter is 50.

http://docs.hp.com/en/939/KCParms/KCparam.MaxAsyncPorts.html

Solution

1. Set MAX_ASYNC_PORTS to a value high enough
2. Deactivate async io at os level.
