Wildfly leave Two Orphaned File Descriptors after uploading a file

Binh :

I'm running Wildfly version 14 and version 18 (on different machines) and Primefaces. Whenever I upload a file, I get 2 orphaned fds. I've doubled checked my code and all resources are closed. I didn't have any problem running Wildfly 11, btw. I also use lsof to make sure that the opened files belong to Wildfly, and they are. Eventually, I get the Too Many Open Files error.

ls -alFtr /proc/30724/fd|grep elete
lr-x------ 1 ora ora 64 Apr  3 09:36 594 -> /PATH_TO/undertow1607766259253292434upload (deleted)
lr-x------ 1 ora ora 64 Apr  3 09:40 591 -> /PATH_TO/undertow1607766259253292434upload (deleted)

Googling the problem gave me several RedHat links, but I can't find any solution to my problem. Any ideas?

Yes if you are using PF 7.X this was a bug and fixed in PF8.0.
