ERROR 216 - 101 when enabling indexes

Hi, i am reloading tables in a database without logs. database is not compressed. For load i am using external tables then 'insert into table select * from external_table' working on AIX 7.2 with raw devices. The script uses dbaccess on the same machine than informix server. Problem encoutered on 12.10FC14 and 14.10FC5 i have 4 connections, each one disabling triggers, indexs and reloading different tables. When all tables are loaded then indexes and triggers are enabled again. All is working fine but sometine i get the following error randomly, not always on the same table. set pdqpriority 20;PDQ Priority set. set indexes for artcle enabled; 216: Cannot remove index. 101: ISAM error: file is not open. Error in line 424Near character position 48 set triggers for artcle enabled; Mode set. set pdqpriority 0;PDQ Priority set. I am alone on the server and the problem is not always on the same table. Does anyone has in idea about this problem ? The SQL corresponding : set pdqpriority 20;set indexes for ${tab} enabled; set triggers for ${tab} enabled; set pdqpriority 0;On this example the table doesn't have any trigger nor constraints. The database owns about 500 tables and i reproduced the problem just 1 time for 10 tried to load all the tables Regards ------------------------------ jean-francois BOUDRY ------------------------------ #Informix

by lowering pdqprioroty from 20 to 10, it seems to be more reliable. 50 tests without error. But it don't have any explanation about that. ------------------------------ jean-francois BOUDRY ------------------------------
