I execute the shell to clean system cache when jenkins runing : echo 3 > /proc/sys/vm/drop_caches
I integrated jenkins with ldap.
Then, jenkins login UI has been loaded.After a long time, it's logged in.
I can click system configration,etc. But can not click enter in a job when is running. After long time,the job build is back to normal.
Sometimes ,someone can log in ,it looks nornamls.But others cannot log in.
The user interface is always showing calculations.

Looking forward to your reply~Thanks.
