yep I read it but that key does not exist in ubuntu and hence is not exposed. ( At least in the 10.4LTS which we are using) I dont believe this is the real issue anyway though as I can do the opposite and increase solaris to 60 seconds. The behavior does not change and TIME_WAIT should only impact the server and not the F5. Meaning if that was an issue , I should see problem with socket creartion for new connections as there would be to many in TIME_WAIT. That is not the case here , so there is something else wrong.
THere is NO way to modify TIME_WAIT on ubuntu 10.4 and I have not looked into new versions but I dont beleive that has changed. I will have to go and double check.
