DB2AIOTHR SEEMS TO STUCK IN THE SOLARIS KERNEL |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problembeschreibung: |
DB2 instance on Solaris can become inaccessible and
enter a hung state.
After a period of activity a DB2 instance became inaccessible
and entered a hung state.
Looking at the DB2 threads they can been seen to be on async I/O
requests. However the Solaris async I/O worker threads all
appear to be idle and waiting on requests.
This can be due to a Solaris defect 6972029 close(-1) cancels
all aio for all open file descriptors. |
