Has anyone seen this error? err.PersistenceService

Question

On my Domino server (9.0.1, FP2) I am getting the following error.

11/20/2014 01:00:39 PM HTTP JVM: !err.PersistenceServiceResourceProvider.Errorwritingtopersistedcontenttor!. For more detailed information, please consult error-log-0.xml located in D:/Program Files/IBM/Lotus/Domino/data/domino/workspace/logs

When I look in the log-0.xml file I see errors like the following. Anyone else ever see this before? I searched the web and only found something similar back around 8.5.2 days.

Answer 1

The persistence provider is used when files on the disks are accessed. This can be persisteted attachments (for CKEditor) or global resources like JS libraries or CSS files (stored in notesdata/domino/)

In your case, it seems that a resource could not be found / is missed. Please check all URLs (e.g. with a Firefox extension like Firebug to sniff the traffic between client and server) which the browser wants to open before the error occurs. The URL should contain a /.ibmxspres/.

UPDATE:

The error can also occur because of an attachment in a RichText item. When you open a CK Editor, all files are detached to disk in a persistence folder, so the CK Editor can display them (or the files can be downloaded)

As soon you open a URL with xsp/.ibmmodres/persistence/, the resource servlet will try to open the file at the end of the URL (/DominoDoc-CD2-Body/_1_14129733906‌​540-76E.gif) and send it back to the client. But when a session times out, or the server is restarted, these persisted files are discarded from disk and are no longer available.

In your case, the Bing Bot has crawled your page and found such an persisted file. And now he wants to check if this file still exists (which is no longer the case). That's why the servlet throws an error.

Answer 2

Add this to your web server's robots.txt file:

User-agent: *
Disallow: *SessionID=*
Disallow: /yourwebsite.nsf/xsp/.ibmmodres/persistence/

and use Google's WebMaster tool to tell Google that your robots.txt has changed. Instantly no more error messages!

Answer 3

Thanks to Sven's info. and some digging it appears there is no issue with our environment, just bots trying to access resources that are no longer available.
