We have experienced this problem, but have had to use greater delays in
the timing. 

#define         RegistryRetry   10
#define         RegistrySleep   20


 /* Loop til user has been added to the Registry or the RetryLimit is reached 

       for (i = 0; ((!add_usr_rgy_ok(dir)) && (i < RegistryRetry)); i++) {
         call_registry(batchfile); /* system call with a shell script */
         fprintf(logfd,"[SYS_ADMIN] add_usr_rgy: Sleeping waiting for ...
         sleep(RegistrySleep * i);
        }


There has been an application written by the Specials Group (sp?) at
APOLLO to provide a  NIS(YP)/Registry interface where updates from
flat NIS files are updated into the Registry. I assume that this application
is using a registry API.

Our scheme here seems to work with ~180 node networks with about 10 registry
slaves.

tony
