  A later post indicates the problem was resolved by a PTF; thus 
this is just FYI, more generally.

  FWiW, the above stack indicates the change file processing took 
an unmonitored exception msgXXX#### T/QDBCHGFI TM/QDBCHGFI 
STMT/17910 such that the Default Exception Handler took control. 
Presumably that exception is then handled, but in a manner which 
then results in a loop vs hang condition; depending on the inquiry 
message reply handling, such a loop could be a side effect of a bad 
auto-reply.  A trace would show more detail; many refreshes of the 
stack view may also show more details, but less efficiently and 
easily missing much.  If instead the condition were a hang [in RUN, 
or at least other than MSGW or LCKW], then the previously noted LIC 
process dump would be of more interest.
