Re: [Pound Mailing List] "Too many open files" errors running pound 2.5-1.1 on Ubuntu 12.04

Hi Nigel,

OK thats fine.

Do you have 'Alive', 'TimeOut' and 'ConnTo' values set in your Global or
BackEnd sections?
By default the Alive section is 30 seconds and the TimeOut & ConnTo is 15
seconds you may also find that a 'Grace' setting increase may help.

Although if you are just terminating an SSL Certificate and then trying to
Load Balance over multiple backend servers you may want to have a look at
HAProxy and let that do the heavy work instead of Pound. You will also get
better debug logging (thats just my opinion though).
