Good morning,
we have Liferay Portal 7.1.3-ga4 installed in a cluster composed of two nodes.
For some time now, only on one of the two nodes, Liferay has been continuously writing huge ZIP files, dozens of GB in size, into the temp folder.
The application server tries to delete these files but fails to do so, and they remain pending, eventually filling up the disk of the machine and causing the application server to crash.
When we restart the application server, the files get deleted.
Do you know why this is happening?
How are temp files managed?
How can we resolve this issue?

Thank you,
Francesco
