----------------------------------------
That's indeed a good point Ingo. We could then close this issue, what do others
think?

> Key: OFBIZ-2208
> URL: https://issues.apache.org/jira/browse/OFBIZ-2208
> Project: OFBiz
> Issue Type: Bug
> Components: framework
> Affects Versions: Release Branch 4.0, Trunk
> Environment: any
> Reporter: Karim Rahimpur
> Assignee: Jacques Le Roux
> Attachments: ServerHit.patch, ServerHitBin.java.patch,

> org.ofbiz.webapp.stats.ServerHitBin.saveHit(...) causes transactions to be
> aborted due to duplicate PKs.
> The problem is that said method will try to create two or more entries with
> identical startTimes (i.e. duplicate hitStartDateTime and the other fields
> composing the PK: visitId, contentId, hitStartDateTime, hitTypeId) if two or
> more subsequent requests are made in a sufficiently small interval. This can
> and *will* be the case for example if an application rapidly issues requests
> for similar data. It would usually not be observed when human users cause
> requests being issued.
> The cause is that the above mentioned method uses
> serverHit.create();
> to store the entries.
> A solution to this is to _create or update_ an existing entry, thus
> overwriting an existing entry in case there already was an entry, but more
> importantly avoiding the actual transaction being aborted. This may not
> satisfy those who want to record each and every server hit even with equal
> startTimes. For these cases other approaches might be considered ...
> This is an example where a transaction fails due to saveHit(...). In our case
> an applet tries to pull data off the server and fails ...
