Symptom: A memory leak is observed on the Core device after a while of handling SMB traffic. This can be confirmed using the 'top' command where the smb process is taking more then 60% of memory. When the SMB traffic stops the smb process memory usage remains high. Conditions: The device was not overloaded and showed no alarms or outwards signs of high load. The user symptom was that CIFS operations became very slow, especially directory listings would become slow. In traces we can see that sometime listing a directory takes 8 seconds when normally it takes a fraction of a second.
