Kernel cannot send, host process disconnected: Linux 15871 SUID: 1 kernel RT _ dpoll: correcting

When I used bcp to back up data yesterday, the following error is always prompted and only several large tables can be exported at a time. This made me very strange that I failed to try it several times in a row.

Later, the database prompts that the temporary database tempdb is not large enough. When I plan to allocate 2 GB space to him, I find that the allocation of space is always failed. After checking the day, I realized: it turns out that the device file is used up, after the problem is found, it will be easier to do more. Use YaST's partitioning tool to create a New GB space and create the Backup Directory and new device files to the new partition, then things couldn't be better!
