DB2 FOR LUW / DB2FORLUW / A10 - DB2

In some cases the db2vend process might fail to attach server 
shared memory segments that belong 
to the database memory set. Messages like the following will 
appear in the db2diag.log file: 
 
  2013-03-11-11.31.34.862818-240 I89558391A1173       LEVEL: 
Warning (OS) 
  PID     : 2622752              TID : 1              PROC : 
db2vend 
  FUNCTION: DB2 UDB, SQO Memory Management, sqlocshr, probe:210 
  MESSAGE : ZRC=0x850F00C4=-2062614332=SQLO_ADDR_CONFLICT 
            "An address space conflict was detected attaching to 
shared memory." 
  CALLED  : OS, -, shmat 
  OSERR   : EINVAL (22) "Invalid argument" 
  DATA #1 : Memory set handle, PD_TYPE_OSS_MEM_SET_HDL, 48 bytes 
 
This will happen only in a few cases where the db2vend stays 
alive long enough for 
the database server to grow the database memory set with a few 
additional shared memory 
segments. The problem here is that the db2vend will somehow try 
to attach again a segment 
it already attached at that given address. Note that to 
differentiate this from a genuine error 
a truss/trace/strace... would show that the db2vend is trying to 
shmat() a segment with segid ID 
at address ADDR but a pmap would already show that same segment 
with segid ID attached 
at address ADDR. 
 
When that problem occurs, if the db2vend stays alive long enough 
multiple occurrences of 
this message will appear in the db2diag.log.
