After running a Pipeline script, build slave agent or Jenkins master has a unusual number of open FIFO files. These are not linked to a process anymore.
- JDK 6
- Pipeline plugin
On JDK6, garbage collector is not always collecting open FIFO correctly. Closing these descriptors might require a major garbage collection.
Customer are advised to upgrade to JDK 7 or 8 to fix this issue. Please take a look at our supported JDKs page.
