Goldengate ERROR: sending message to EXTRACT (Timeout waiting for message)

Hi,

My pump process was hang and it was not go ahead.

 

When I try to stop it, i got the following error.

GGSCI (msddp01.deveci.local) 3> stop P01MSD1
Sending STOP request to EXTRACT P01MSD1 ...
ERROR: sending message to EXTRACT P01MSD1 (Timeout waiting for message).

 

 

To solve this problem, kill the related process then start it again.

 

GGSCI (msddp01.deveci.local) 4> kill P01MSD1
Sending KILL request to MANAGER ...
Killed process (243210) for EXTRACT P01MSD1
