SUSE Linux Enterprise Server 11 Service Pack 3 (SLES 11 SP3)
@namespace url(; @-moz-document domain("") { .bz_comment { margin: 0 0 20px; width: 100% !important; } .bz_comment_text { width: 100% !important; } }SUSE Linux Enterprise Server 11 Service Pack 4 (SLES 11 SP4)


After updating to kernel version 3.0.101-108.38.1 or version 3.0.101-108.41.1 storage backups were starting to fail. The DB2 errors pointed to ipc (interprocess communication) related errors.

The DB2 log (db2idag log) is showing an error like this:
FUNCTION: DB2 UDB, database utilities, sqluBufInUse, probe:1453
MESSAGE : SQL2044N An error occurred while accessing a message queue."


The SLES11 SP4 kernel update: 3.0.101-108.52.1 and SLES11 SP3 LTSS kernel update: 3.0.101-, both released May/31 include the patch to resolve the problem.


Cause is a faulty parsing of msgctl args in a fix of an ipc data structure inconsistency.
