Hello everyone
I am currently experiencing an issue that I cannot explain to myself.
I am currently migrating our XWiki Debian 15.10.11 to a new Xwiki 17.3.0 WAR installation (Windows Server 2022).
Now I have reached the point where I want to migrate the content of the wiki, and I am encounterting the following issue.
I have successfully exported the Wiki content from the old Wiki. I successfully uploaded the Wiki content to the new Wiki (2GB, almost 5 thousand files).
Now I select the available package. The file structure is shown correctly.
I select a large directory and then on import. About half a second later this error appears:
I checked the logfiles and there is a total of zero logfile entries at the time of the error.
I have done the following things to troubleshoot already:
I checked the maximum attachment size according to this article. It is 100GB, which should be enough.
I have verified that I have enough drive space available.
I have increased the usable amount of ram for tomcat from 4GB to 8GB to improve performance during the import process.
I am able to import smaller directories that contain less than 100 files.
However due to the amount of migrated pages and due to the folder structure, it is not feasible to do this in smaller batches.
At this point, I suspect that I might be limited by some performance setting, but I have no idea which one.
