| OS | Gaia |

## Symptoms

- * Security Gateway running Identity Awareness get "`Table "pdp_sessions" entries limit (90000) reached`" in SmartLog.
* Security Gateway running Identity Awareness get "`Table "pdp_super_sessions" entries limit (30000) reached`" in SmartLog.

## Cause

* Identity Awareness kernel tables are limited to the following by default:

pdp_super_sessions: limited for 30,000 entries.

pdp_sessions: limited for 3 X pdp_super_sessions limit (90,000 entries by default).

* Until R80.10 GA, Identity Awareness can associate up to 30,000 IPs (=pdp_super_session entry) per gateway. Therefore, we have limited the kernel tables.
* In some cases, even when the environment has less than 30,000 IPs, the kernel tables are overflowed. This usually happened due to service accounts.
