Solution :
§ Linkchecker performs a lot of JCR
writes/update causing CPU peaks as well as performance decreases, mainly caused
by the JCR locks.
§ To verify if the repository
growth is related to the linkchecker, enable TRACE log level for
org.apache.jackrabbit.oak.jcr.operations.
§ Writes during a few minutes, and
check if the majority of the writes are below /var/linkchecker. Then do not
forgot to disable the TRACE log level.
§ In such cases where performance
is compromised by this linkchecker behavior, it is recommended to disable this
feature by following the steps below:
1. Delete /var/linkchecker (it
will be recreated automatically)
2. In the
OSGI configuration console, open Day CQ Link Checker Info Storage Service and
deselect "Save external link references” option and save.
Note:
Please note
that, disabling this option will not cause automatic removal of the
existing referencedBy property values. To achieve this,
first remove /var/linkchecker.
