I am running AIX on IBM RT. Some of my users complain about the "at" command. When they try to issue a number of jobs that start at same time using "at" command. They got some jobs never execute. I found the problem is too many jobs being scheduled. I tried to duplicate the problem, it seems to me more than five jobs start to have this problem (not yet confirmed, I am still running some tests to test it out). "Cron" try to reschedule jobs when one job is still running and the other jobs should have started according to their scheduled time. And some how the jobs are not schedule well and state in the queue. Also I found "at" may start two jobs at the same time ( I don't know whether this is legitimate, but most of time "at" only invoke one job ) Have anyone out there experienced this problem before and show me how to solve it. Or does anybody know how "cron" reschedule jobs. Thanks in advance.
