    Description

      I'm fighting against periodic XWiki hangs. When application becomes unresponsive, I generate java threads dump and see 1500+ threads like this:

      "Thread-325900" #325988 daemon prio=5 os_prio=0 tid=0x00007f3f9ce56800 nid=0x773 runnable [0x00007f3ee500a000]"Thread-325900" #325988 daemon prio=5 os_prio=0 tid=0x00007f3f9ce56800 nid=0x773 runnable [0x00007f3ee500a000]

      Authentication itself works perfectly. Any clue why does it spawn so many threads ? It makes the XWiki almost unsuitable for production use. I have to restart it 3-4 times a day.
