Hi to everyone.

We are experiencing some exceptions of this type:

DatabaseException BIP2322E: Database error: SQL State '57033'; Native Error Code '-913'; Error Text '…DB2 for OS/390Š…
DSNT408I SQLCODE = -913, ERROR: UNSUCCESSFUL EXECUTION CAUSED BY DEADLOCK OR
TIMEOUT. REASON CODE 00C90088, TYPE OF RESOURCE 00000304, AND RESOURCE
NAME DBWIMSG .WISBSND .X'000174' '.X'0F'
DSNT418I SQLSTATE = 57033 SQLSTATE RETURN CODE
DSNT415I SQLERRP = DSNXRRC SQL PROCEDURE DETECTING ERROR
DSNT416I SQLERRD = 102 13172746 13172872 13228501 -404549624 536870912
SQL DIAGNOSTIC INFORMATION

X'E7E31008' X'20000000' SQL DIAGNOSTIC INFORMATION
ERRLOC=1:13:2'.
The error has the following diagnostic information: SQL State '57033' SQL Native Error Code '-913'
DSNT408I SQLCODE = -913, ERROR: UNSUCCESSFUL EXECUTION CAUSED BY DEADLOCK OR
TIMEOUT. REASON CODE 00C90088, TYPE OF RESOURCE 00000304, AND RESOURCE
NAME DBWIMSG .WISBSND .X'000174' '.X'0F'
DSNT418I SQLSTATE = 57033 SQLSTATE RETURN CODE
DSNT415I SQLERRP = DSNXRRC SQL PROCEDURE DETECTING ERROR
DSNT416I SQLERRD = 102 13172746 13172872 13228501 -404549624 536870912
SQL DIAGNOSTIC INFORMATION
DSNT416I SQLERRD = X'00000066' X'00C9000A' X'00C90088' X'00C9D9D5'
X'E7E31008' X'20000000' SQL DIAGNOSTIC INFORMATION
ERRLOC=1:13:2'

What is strange and we are not able to understand is that this exceptions happen when we try to access the SAME table BUT in DIFFERENT rows of it; because of the dimension of each record is 32k, what probably happens is that the whole page is locked....

Anyone able to suggest a direction where to investigate?

Thanks
