java.io.IOException: The requested operation could not be completed due to a file system limitation
0
We're getting a large amount of exceptions in our production environment while handling webservice calls. We published a webservice and one of the child entities has a base64 encoded string which is mapped to system.FileDocument. This one is causing trouble. We're running the app on premise and the [project-directory]/data/files/ directory contains a huge amount of files, but the disk is not full yet. Restarting the app didn't help. Any help would be appreciated. Edit after solution: It was caused by too many files in the /tmp/ directory. More than 2.1 million. We changed the /tmp/ directory to another directory and that solved the problem. It seems that Mendix doesn't remove the temp files in that directory. com.mendix.core.CoreRuntimeException: com.mendix.core.CoreRuntimeException:
