My best guess is that it has something to do with XWiki running on an Amazon EC2 instance. I didn't see the same kind of issues on a local machine.

Thanks for the information and indeed you could be right about the Amazon EC2 context for the futex problem. I don’t have any experience with running XWiki on Amazon EC2 so I cannot help much, sorry.

[xwiki-users] Futex errors
by Aaron Hardy at AC 20 Feb '15

20 Feb '15

Trying to track down the source of some persistent performance issues under load with 6.2 RC 1 (haven't had time to upgrade to 6.2 final yet). I'm maxing out at about 30 or so users before dying on a system with 4GB of RAM. The java interpreter is getting pegged to 100% of the CPU, and about 70% of the calls in the stack trace are futex lock errors. A good chunk of the remainder are gettimeofday calls. Potentially useful info (sorry for formatting): % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 72.75 5361.592109 45075 118947 14045 futex 12.28 905.064191 466 1943354 gettimeofday 4.83 356.110745 3709487 96 45 restart_syscall 2.88 212.173358 836 253729 clock_gettime 2.71 199.867690 8802 22706 recvfrom 2.10 154.843342 37841 4092 poll 1.14 84.282371 580 145307 130153 stat Any ideas? thanks, aaron

I cannot remember what exactly these were because I'm not sure what all was contained in the default wiki pages .xar file.

[xwiki-users] Failed to execute the [groovy] macro while creating an app within a minute
by Peter Duever 20 Feb '15

20 Feb '15

Hello XWiki Community, while creating an App within a Minute I get groovy executing failures for each element of the form. It is possible to save and finish the process but I cannot access the editor for the content field. That means I cannot enter default entries. You can see the full failure message at the end of the mail. I googled the problem and found entries for Confluence. Maybe they can guide a way: Now I added the "-XX:ReservedCodeCacheSize=64m" option into JAVA_OPTS. (https://bobswift.atlassian.net/browse/SCRP-129) and It worked for me, I just added XX:ReservedCodeCacheSize to my setenv.sh and until now everything is ok. (https://answers.atlassian.com/questions/13535/problem-with-the-script-runne…) I am running version 5.4.5 Thank you for your time! Best regards, Peter Here is the error which is displayed when I reenter the wizard page for step 2: Failed to execute the [groovy] macro: java.lang.VerifyError: (class:

[xwiki-users] Default Wiki Pages XML Files not Installed
by Erin Kelley 20 Feb '15

20 Feb '15

Hello, I setup a Tomcat server with a MySQL database and am trying to setup Xwiki on it. I followed the administrator installation guide and ran into a problem that I can't seem to find the solution to. Everything seemed to work properly until I tried to import the xwiki-enterprise-ui-mainwiki-all-6.4.1.xar. After the import was done, I was shown a list of files that were installed as well as the ones that were not installed. It seemed that none of the xml files were installed. Has anyone ran across this issue before? I can still navigate across the wiki, but, for instance, when I click on the admin's profile or preferences, no text boxes or buttons of any kind appear. It pretty much shows just a blank page. Any help would be appreciated. Thanks!

[xwiki-users] Black gallery after PowerPoint import
by D R 20 Feb '15

20 Feb '15

Hi guys, we discovered an issue with XWiki 6.3. After importing a PowerPoint presentation from within the WYSIWYG editor and saving the page the presentation is added to the attachments but the document shows a black gallery with 0/0 slides. In the log files I don't see any errors concerning this. We're on Windows Server 2003 R2, Tomcat 7, JDK 7, Apache 2.4, Libre Office 4.3 Is this a bug I should report a Jira about or is there something you can suggest to me? BR, Dennis

I'm updating XWiki translations in http://l10n.xwiki.org/ and after resource redesign I wonder where should I start. Can you provide some list of description/priorities for all XWiki platforms and files, which should be translated first to cover needs of the most usual XWiki users. Thanks! Valdis
