mysqld in hung mode

Hi,

 

Today our mysqld process is in hung mode. I'm able to connect to mysqld
thru mysql client, but none of the commands are going thru.

I tried 'show processlist' and 'select 1' from mysql client, the command
just hangs.

In the task manager I can see mysqld in running and its cpu usage as 0.

Any idea why mysqld is in this state?

 

Is there any command that I can use to see the state of the mysqld? 

 

Ila.
