Hello everybody, a few days ago I uploaded a folder of files (.doc, .txt, .pdf,....) on my Alfresco server (201707GA), then I noticed that CPU load started increasing uninterruptedly, reaching a CPU load of 400% and over. I tried to restart Alfresco server, but CPU started again to increase until the server was unusable. Searching on the forums I enabled debug log for Alfresco transformation:
log4j.logger.org.alfresco.repo.content.transform.TransformerDebug=DEBUG log4j.logger.org.alfresco.repo.content.transform=DEBUG
and after enabling these settings, in the log files I noticed a lot of lines regarding the transformation of a single file:
2020-02-07 00:05:30,299 DEBUG [content.transform.TransformerDebug] [http-bio-8443-exec-700] 68 pdf txt document_of_deployment_ugpa.delay_NO DATA_.pdf 803.9 KB -- index -

this sequence of lines repeated about every 5 minutes for about 150 times...I deleted that file from Alfresco and the server load returned normal.
Now my question is: is there a way to avoid this behaviour, without disabling Alfresco transformation? Maybe limiting the number of retries?
Is it an issue related to document preview or indexing?
