ERROR During call of SOAP with a SOAP- RFC- SOAP Synchronous scenario

Question

Hello Experts,
I've recently created a SOAP->RFC->SOAP synchronous scenario but every time I'm invoking the SOAP via XMLSpy then i will hang and send a timeout error. Also a log in XI was generated as shown below.
I hope you could help me on this one.
Runtime Errors         DBIF_RSQL_SQL_ERROR
Exception              CX_SY_OPEN_SQL_DB
Date and Time          28.09.2010 09:31:23
Short text
     SQL error in the database when accessing a table.
What happened?
     The database system detected a deadlock and avoided it by rolling back
     your transaction.
What can you do?
     If possible (and necessary), repeat the last database transaction in the
      hope that locking the object will not result in another deadlock.
     Note which actions and input led to the error.
     For further help in handling the problem, contact your SAP administrator
     You can use the ABAP dump analysis transaction ST22 to view and manage
     termination messages, in particular for long term reference.

Error analysis
     An exception occurred that is explained in detail below.
     The exception, which is assigned to class 'CX_SY_OPEN_SQL_DB', was not caught
      in
     procedure "DELETE_LUW_PACKET" "(FORM)", nor was it propagated by a RAISING
      clause.
     Since the caller of the procedure could not have anticipated that the
     exception would occur, the current program is terminated.
     The reason for the exception is:
     The database system recognized that your last operation on the database
     would have led to a deadlock.
     Therefore, your transaction was rolled back
     to avoid this.
     ORACLE always terminates any transaction that would result in deadlock.
     The other transactions involved in this potential deadlock
     are not affected by the termination.

Answer 1

Normally such an error comes when the DB of SAP PI is full.
Contact your BASIS or ADMIN team and ask them to free the DB space.
