I checked several lab cases, and have these suggestions:
Delete, or comment out the file
SmWaitForFirstBackupClientSec=1200
and, in its place, add
SmWaitForFirstBackupClient=600
This value is expressed in MInutes instead of seconds (1200 seconds is 20 minutes)
I'm not sure about this one, it seems to me that 20 minutes would be plenty long enough

You did not state what version of DP you have, but I found that versions 6.21, 7.01, and 8.x have been patched to fix this problem. It appears that 2 shared libraries were not loading successfully
