Problem creating indicies (7.20.UC2 Solaris 2.5)

Hi, I have a process that drops a table, recreates the table, and loads about ~80k rows back in. As the final step it recreates the indicies for the table. What I am finding is that I can't create the indicies too quickly. By that I mean that if I do two or more "create index" commands on the same table the second one fails with: 242: Could not open database table (user.table_name). 113: ISAM error: the file is locked. I have run every oncheck option there is and it found no problems. If I wait about 30 seconds or so the next create index will work just fine. On tables that have very few rows this isn't a problem. This is a dual processor SS20 running Solaris 2.5 generic, 7.20.UC2 Online, replicating to another system. No one else is in the dataserver when this occurs. Any help would be appreciated.
