DeletedNodeCleanupWorker fails to purge deleted nodes in DB

Jump to solution

Hello,

I am using Alfresco Community - 5.2.0 (re21f2be5-b22) and I am facing some issues with deleted nodes DB purging as stated below.

Has anyone encountered the same issues?

Are there any config parameters to change in alfresco-global.properties or any manual recipe to fix this issue?

Any help would be much appreciated.

Thanks in advance,

Luis Alventosa

Under a specific constellation involving concurrent deletion + cretion/change on other nodes, previous versions of Alfresco could run into issues where it tried to purge non-deleted nodes, which fails because of those foreign key constraints. This should be fixed as part of REPO-3493 for ACS 6.1. It can be worked around by manually purging deleted nodes via SQL - once all currently deleted nodes have been purged, ACS should continue normally with regular purging (at least until the specific constellation is triggered again).
