Due to "No space left on device", Many Concurrent Manager are under 'No Manager' Status

Found Many Concurrent Managers are under 'No Manager' Status, Then I tried to restart Concurrent Manager like(http://blog.csdn.net/pan_tian/article/details/7765256)

Then saw following error:

It's clear in Oracle DB Side,sql trace are too big under user_dump_dest dir.

After remove all sql trace from user_dump_dest,concurrent manager works.
