[Strange problem] LTM virtual server sometimes not forward traffic to pool

I have seen in ver 9.x where a new pool sometimes would just not have a pointer or something associated, and it just wouldn't accept traffic, deleting the pool and recreating it worked to fix it.

 

 

In version 10.x I've had issues after I run a reload license command - where irules that were pointing to a pool that wasn't associated with a vip, were no longer working, in that case also the stats on the pool would not clear out, even if you deleted the pool and recreated it, that stats would come back, and at time's I've had to rebuild the pool under a new name.

 

 

Not sure if your running into either of those issues, I might the issues in Ver 9, would only show up when the pool was first built, in version 10, I've not seen that, so far has only been associated when applying a new license.
