If you use plsql to connect to oracle, for more than half an hour and do not operate, it will prompt "no response"?

close also indicates no response, stuck, need to close the process and reopen it?

I often do this, probably because of the design, it's best not to turn it off and use it to open it.

MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
MySQL Error : Disk full (/tmp/#sql-temptable-64f5-1b36cbb-2b7bd.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
MySQL Errno : 1021
