I am facing the below mention problem.
The web application [/helloWorld] appears to have started a thread named [MySQL Statement Cancellation Timer] but has failed to stop it. This is very likely to create a memory leak.
i am using the mysql-connector-java-5.1.25-bin.jar which is latest one but it is still giving the problem.
Please help me.

From the command line window in linux atleast - "ps -A" will give you a list of all your processes - dont type the quotes. You can confirm that it is in that list or just type "ps -A | grep MySQL Statement Cancellation Timer. This will return you a process ID. Then type kill ##### (whatever your process id is that you want to kill). Hope that helps

exit
mysql -u user -p
I’ve tried on several times but same happened then I completely uninstalled and install MySQL again, but the result was same.
What may be the reason for this? How to fix this issue?
Maybe the Commit; Statement can help you.
But please help us first by showing us some code. Then we maybe able to help you more efficiently.
See link for more Information on Commit:
https://www.studytonight.com/dbms/tcl-command.php
To give you the essential points from the link:
COMMIT command is used to permanently save any transaction into the database.
When we use any DML command like INSERT, UPDATE or DELETE, the changes made by these commands are not permanent, until the current session is closed, the changes made by these commands can be rolled back.
To avoid that, we use the COMMIT command to mark the changes as permanent.
The code is realy simple, make all you changes and then use:
Commit;
Thats all. Just remember that you can rollback at a maximum 1 commit ;)
-> So changes become permanent after the second "Commit"

I am looking for a way to backup MySql database use a C program. Does MySql provide API for backup?
No, mysql does not provide any dpecific api to back a database up.
Mysql does provide the mysqldump utility that can be called from the command line to back up a database and also provides a general C api to access a mysql server. The heneral api can be used to write your own backup program if you are unhappy with mysqldump.

There are jobs running on the GPU, and if I run another code on top of it, the code stops at the point of cudaDeviceSynchronize(). Why does this happen?
Currently only one process is allowed to use a GPU at a given point in time. There is no fairness nor quantum to kill a ''job'' in case it runs for hours in a GPU. The basic usage is first come first serve.
But you may use the CUDA Multi-Process Service (MPS). It basically allows multiple processes to share a single gpu

How do I count the number of mysql processes running and the number of mysql connections? What is the relationship between these two numbers?
There is no distinction between "processes" or threads when running one server. Multiple process show up due to the way the host OS "sees" the threads spun up by MySQL.
If you are sure you only started one sever, you can check the number of actual processes by running: ps auxww|grep mysql
You can also limit the number of connections by setting: max_user_connections in your MySQL configuration.
If you have multiple MySQL instances running, you can check your threads by running: show full processlist
