When IMSI based conditional debugging is enabled on a 
co-located controller/member, PDSN may crash.

Use NAI based 
conditional debugging 
instead of IMSI based 
condition.

Users are unable to setup session when subscriber 
count reaching almost near  to the max configured 
pool range  due to address allocation or address 
distribution limitation in single ip . With the 
present single-ip ip pool distribution logic, 2 out of 
7 parts(total pool / 7) are held with Pcop, and 
remaining 5 are distributed such that one to each 
Tcop.

Due to this there are so many IPCs, and due to IPC 
failures, some time Tcop may not get the IP address 
though there is enough free chunk of pool range 
with the Pcop. 

Configure extra 
IPs, if possible.

Less idle-timeout 
value also frees the 
aged users, and 
that way more IPs 
with the Tcops.

Whenever the port range is configured in the packet filter 
the PDSN RTP data is not flowing through the A10 
auxiliary connections.

Configure the port 
number in the mobile 
node rather than the 
port ranges in the 
packet filter.
