Confluence Cache Exception

One of our user macros is throwing a 'Broken Macro' error.
 
We keep seeing this error since the reports of the broken macro

com.atlassian.cache.CacheException: java.lang.NullPointerException

We've tried increasing the logging level on com.atlassian.cache.CacheException which doesnt result in anything extra.
 
Cache has been cleared / Confluence restarted.
 
Have you experienced this before?

Yes, but you've tried the first thing that usually fixes it.

We will need to see more of the log around the error, and probably the macro definition as well.

Hi Nic,

Thanks for taking a look.

Macro Definition - everything was taken out of the definition but the error still persists.

Even with the macro deleted we still get the error =

Errors from log :

{ "message": "com.atlassian.cache.CacheException: java.lang.NullPointerException", "time": "2017-07-21T10:37:14+01:00" }

{ "message": "com.atlassian.cache.CacheException: java.lang.NullPointerException", "time": "2017-07-21T10:37:14+01:00" }

{ "message": "com.atlassian.cache.CacheException: java.lang.NullPointerException", "time": "2017-07-21T10:37:14+01:00" }

 

Strangely this occurred a few months back and resolved itself without any manual intervention.

Without the macro definition, I can't really get a grip on this at all.

However, there is another thing to try - delete the user macro completely (as you've blanked it out, it's not doing anything anyway).   Re-index Confluence, and restart it.  You should then get pages with "unknown macro" on them, but it should have cleared out all the caches.

Deleted Macro which resulted in no immediate effect. Left for 24hrs~ and then we got the 'unknown macro' error. Reinstated macro and all is well again.

Possibly some sort of background indexing that rebuilt caches maybe?

There is caching that will affect data in macros.

If it happens again, then try going to Admin -> Caches.  Look for any cache mentioning macros or page data and flush the cache, then retry the pages.
