Hi!

We are facing these errors from time to time in our two node RAC:


Errors in file e:\oracle\product\10.2.0\admin\db13\udump\db131_ora_28348.trc:~ORA-27508: IPC error sending a message~ORA-27300: OS system dependent operation:IPCSOCK_Send failed with status: 10054~ORA-27301: OS failure message: An existing connection was forcibly closed by the remote host.~ORA-27302: failure occurred at: send_3~




and this:


Errors in file e:\oracle\product\10.2.0\admin\db43\bdump\db431_pz99_20980.trc:~ORA-27508: IPC error sending a message~ORA-27300: OS system dependent operation:IPCSOCK_Send failed with status: 10054~ORA-27301: OS failure message: An existing connection was forcibly closed by the remote host.~ORA-27302: failure occurred at: send_3~ORA-10387: parallel query server interrupt (normal)~




According to some info I found on metalink its due to an instance evection. But I have not seen that, I mean, no users have complained about being kicked out (or other errors in the alert log).

Any ideas what migth cause the above errors?

Regards
Hristo

Do any clues exist within OS log files?

errbcm@bcm-laptop:~$ oerr ora 27508
27508, 00000, "IPC error sending a message"
// *Cause:  This is an operating system/cluster interconnect error.
// *Action: Check the value of errno and contact Oracle Support Services.
bcm@bcm-laptop:~$ oerr ora 27300
27300, 00000, "OS system dependent operation:%s failed with status: %s"
// *Cause:  OS system call error
// *Action: contact Oracle Support
bcm@bcm-laptop:~$ oerr ora 27301
27301, 00000, "OS failure message: %s"
// *Cause:  OS system call error

bcm@bcm-laptop:~$ oerr ora 27302
27302, 00000, "failure occurred at: %s"

bcm@bcm-laptop:~$ oerr ora 10387
10387, 00000, "parallel query server interrupt (normal)"
// *Cause: internal use only
// *Action: this event should never be set externally
// *Comment: commands a slave to leave the server group normally

Does any type of OS Virtualization exist in this environment?
