Hi,
I update my wiki from 7.4.6 to latest 9.11.8 and faced with strange problem.
When I delete user (he is in a group with over 5000 entries) then java thread in RUNNABLE state above 2 hour (and i think process is endless). I try to manually add new user and faced with same problem (each thread take ~ 25 percent of cpu and large ammount of allocated bytes).
In 7.4.6 all works fast enough.
Example of threads dump in attached files.
add_user.txt (10.6 KB)
delete_user.txt (7.2 KB)
Does anyone know cause of this problem?
