Hi,

We are using MINA 2.0.0-RC1 in our production env and we have noticed there are 
excessive number of pipes being used. I am pretty sure I properly dispose the 
connector after use (the number of TCP connection doesn't seem to leak), the 
number of pipes seems to go up and up. After some time, the process runs out of 
file descriptors. I am wondering what those pipes are and is there anything 
wrong I did? Any point is highly appreciated!


Below is just a sample of what those pipe looks like using "lsof" against the 
process:

java    3947 scserver *554r  0000               0,11        0 205632121 
eventpoll
java    3947 scserver *555r  FIFO                0,6          205632122 pipe
java    3947 scserver *556w  FIFO                0,6          205632122 pipe
java    3947 scserver *557r  0000               0,11        0 205632123 
eventpoll
java    3947 scserver *558r  FIFO                0,6          205632124 pipe
java    3947 scserver *559w  FIFO                0,6          205632124 pipe


Thanks,
Yong
