Description: The number of PDP contexts that the activation request rejected due to the GGSN running out of resources for transmitting GTP packets. Examples: - Out of memory; - The number of PDPs on GGSN reached limit; - all dynamic PDP address are occupied;

Trigger Condition: a) Out of memory. b) Number of PDPs on GGSN reached limit. c) Number of of PPP-regen PDPs reaches max limit. d) All dynamic PDP address are occupied. e) Incorrect configs for create pdp req. f) Qos negotiation fails. g) Create PDP req received for non-transparent APN but no radius server is present for authorization. h) Attempt to create a PDP with IP address that is already in use. i) Attempt to create a PPP-Regen PDP but the vtemplate for PPP-regen is not properly configured or VPDN configs are not proper. j) Number of pending signalling messages that needs to be processed by the GGSN is beyond the max limit(100).
