Java VM errors information receiving
Since build 5.2.769 it is possible to get information about certain Java VM errors (exceptions) count with the following query
Code Block | ||
---|---|---|
| ||
http://localhost:8081/?action=stat¶ms=wcs_errors,<exception class name> |
For example, the following query should be peridocally made to control phisical memory lack
Code Block | ||
---|---|---|
| ||
http://localhost:8081/?action=stat¶ms=wcs_errors,java.lang.OutOfMemoryError |
If response contains the exception, and the count is equal or more than 1
Code Block | ||
---|---|---|

-----Errors info-----
java.lang.OutOfMemoryError=4 |
all the clients should be immediately disconnected and te server must be restarted.
