Problem summary

Under specific conditions, Confluence can run out of memory when a user goes to edit a Confluence page or view his drafts (Username > Drafts), following a sequence of events:

User A goes edit a page (Version 1)
Confluence auto-saves a draft based on Version 1, and user does not save the page
User B edits the same page and saves, promoting the page to Version 2
User A views his drafts (or edits the page again)
Confluence tries to merge the three versions (Version 1, Version 1 draft, and Version 2), and results in Confluence hanging

Workaround

Warning:
Workarounds involve deleting one or more drafts. Drafts contain edits that have not yet been saved, so important work can be lost by deleting them.

5.5 and later
If a user has been identified causing this problem, they can go to /users/viewmydrafts.action page and discard either all of their drafts or just the draft for the page that is known to trigger this problem.

5.2 to 5.4
Remove all drafts for the given user (Remember to replace <username> with the username of the user):

DELETE FROM BODYCONTENT WHERE contentid IN (SELECT contentid FROM CONTENT WHERE contenttype = 'DRAFT' AND creator in (SELECT user_key FROM user_mapping where username = '<username>'));
DELETE FROM CONTENT WHERE contenttype = 'DRAFT' AND creator in (SELECT user_key FROM user_mapping where username = '<username>');

All versions
Alternatively, all the drafts can be deleted directly from the DB:

Back up Confluence DB as a precaution

Run the following DELETE statements against the DB:

DELETE FROM BODYCONTENT WHERE contentid IN (SELECT contentid FROM CONTENT WHERE contenttype = 'DRAFT');
DELETE FROM CONTENT WHERE contenttype = 'DRAFT';

Hi florian.rock2 and ryan.goodwin,

I raised to ~~CONF-41610~~ to track this new problem. Thanks for reporting it!

since we reinstall confluence to a clean oracle 12g scheme and reimport data from old scheme we don't have this issue anymore.
We compared and saw that we lost a lot new database indexes over the time from confluence 3 to 5.8.17 ... so may this was causing this issue.

another difference is now that confluence has own oracle database now, before it shared the database with a JIRA Scheme, and when confluence was slow then JIRA also went slow.

I think this bug needs to be reopened. I just got this error in 5.8.17.

Hi bhupesh.nagda1,

I added workaround instructions to the issue description. It should be a matter of the known user deleting a draft for the page that causes the problem. Note that the draft might contain work that the user is not happy to lose. If that's the case, then I would recommend opening a support request.

Cheers,
Olli

I am using version 5.4.1, is there any workaround to resolve this issue? We are not planning upgrade for next one month atleast. Also the error is being faced by single user while editing a single page. Furthermore how can I prepare my users to avoid this problem in future.

Thanks & Regards,
Bhupesh

We have the same problems as you in Confluence 5.4.3.
I think that it is a problem of 3dm library.

The problems are as follows.
https://bitbucket.org/atlassian/atlassian-tdm/src/e55ed4c02e8a073311036811aba1e88a5495c218/src/main/java/tdm/lib/HeuristicMatching.java?at=default#cl-488

HeuristicMatching.java

   private static Measure measure = new Measure();

Why is it "static" here?
Measure instances have two private instance HashMap variables.

https://bitbucket.org/atlassian/atlassian-tdm/src/e55ed4c02e8a/src/main/java/tdm/lib/Measure.java#cl-290

Measure.java

  private Map aGrams = new HashMap(INIT_CAPACITY); 
  private Map bGrams = new HashMap(INIT_CAPACITY); 
  ...

protected void buildQGrams(char[] a, Map grams) {
    grams.clear();
    for( int i=0;i<a.length;i++) {
      int count = i + Q > a.length ? a.length -i : Q;
      String gram = new String(a,i,count);
      if( grams.containsKey(gram) )
        ((Counter) grams.get(gram)).count++;
      else
        grams.put(gram,new Counter());
    }
  }  
  ...
protected int calcQDistance() {
int dist = 0;
// first, loop over agrams
for( Iterator i = aGrams.keySet().iterator();i.hasNext();) {
  ...

I think that there is not the need that is "static".
At first you should change HashMap into local variable.
