Define: inet port exhaustion?

Sorry the first post didn't appear to have taken...

 

 

During various load tests within our environment, I'm seeing the following errors in our logs:

 

 

bigip1 local/tmm crit tmm[5406]: 01010201:2: Inet port exhaustion on 199.83.xx.xx to 10.2.1.140:7304 (proto 6)

 

 

I'm having little luck actually getting a definition of what it means - I assumed it meant number of connections are maxed out on a port...

 

 

Could someone please help with:

 

* General definition of port exhaustion

 

* Is there a known limit? Or, depends on hardware?

 

* Is the limit, per Port/per VIP? Can one port on one VIP being exhausted cause issues with other VIPs or the LTM in general?

 

 

Thanks so much,

There's a SOL on AskF5 about this:

The simple fix is to add more addresses to the SNAT pool and/or create a unique SNAT pool per LB pool. If you need to ensure the same client is SNAT'd to the same SNAT address over connections you can use an iRule:
