The assert subroutine failed

[Stefan Roukens]

On one of our systems with a TSM client 5.5.1.0 we receive the following message when performing a 'dsmc q sched':

The assert subroutine failed: CB_HDRP((char *) blkP - FB_PREVFREE(blkP))->bSize == FB_PREVFREE(blkP), file ../mem/dsmem.cpp, line 1881
Fatal error: got signal 6
IOT/Abort trap(coredump)

The error/core dump only occured when invoking the 'dscm q sched' command and only when performed by a user other than 'root'.

The solution to this was to install patch 5.5.1.11 of the TSM client.
