MR jobs failed on IO and java heap size

Hi,
 
I have a MR job running with 30 reducers, one of the reducers when it reached specific percentage failed with the below error:
 
I increased the reducer memory but with no success, i invetigating the data to find if specific key value has a lot of data and caused this.
 
Mu point i don't get from the below error if it IO issue which might  limited  connections between  nodes then i need to increase the ulimit or it's a memory issue and i increase to increase the memory more
