Problem IT07599
|
Status: Closed |
DR_PRPING THREAD MAY BECOME STUCK IN RUNNING STATE FOLLOWING HDR CONNECTION FAILURE |
| product: |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 |
| Problem description: |
The dr_ping thread may become stuck in a continuously running
state following a connection failure with the HDR secondary
server. The stack for this thread will be similar to the
following:
mt_spin_lock_wait()
asf_checkexp()
sqscb_cleanup()
destroy_session()
dr_primary_ping()
startup()
In addition the command onstat -g ath will show the dr_prsend
thread waiting on the dr_prping thread, for example:
ifx$ onstat -g ath | grep dr_
202 7000000501f80d0 700000020423e68 1 join wait 1116
10cpu dr_prsend
1116 700000050741028 700000020429cf0 1 running
10cpu dr_prping
Once in this state the HDR connection cannot be re-established
until the primary server is restarted. |
