SYMPTOM(s):
WDOG message: User died holding shared memory locks. (2522)
Begin ABNORMAL shutdown code 2 (2249)
User died with buffers locked. (2523)
User died holding shared memory locks. (2522)
FACT(s) (Environment):
All Supported Operating Systems
Progress/OpenEdge Versions
CAUSE:
If the watchdog or server detect that a user is listed in the Progress
user control table but does not have an active UNIX process, the
user will be disconnected from the Progress database and the
following message will be written to the log file:
Disconnecting dead user . (2527)
If the user's process terminated abnormally while holding latches
(locks) in shared memory, a message similar to the two shown below
will be written to the log file:
User died holding shared memory locks. (2522)
User died with buffers locked. (2523)
If shared memory or buffer latches are left in an inconsistent state,
the server will shutdown the database to protect the integrity of the
database. The following message will be written to the log file
followed by all users being logged out and the server shutting down:
Begin ABNORMAL shutdown code x (2249)
The error does not indicate any data corruption. Rather, the
shutdown occurs to prevent any possibility of corruption. Upon
re-starting the database, crash recovery will be done and the database
will be ready for normal use.
FIX:
Restart the database.
