I made a search through PRT builds and found the putback responsible for the failure:
     20040302154502.jrose.tiger

There are 3 steps of the search in the log below:

=========================
(1) Search in the service_hs_baseline

yy prt_find1 service_hs_baseline c2 nsk2 wrong mdp fastdebug [END: Wed Mar 17 16:46:19 PST 2004]


So, the regression came from the merge with main/baseline: 20040304112129.dcubed.service_hs_merge
