Thanks for the feedback, Nick, and Andrea too. It’s been about 2 hours since I changed the setting and I haven’t received an error notification yet, whereas before I was getting one on average every 10 minutes.

According to the man page the version I'm running uses 128 threads by default, but offers a "Threads" global directive to adjust this. I just changed this to 512, so we'll see how that affects it. I've been getting notifications all morning about the service restarting, so if we can go an hour without one I think we're in good shape. I'll let you all know if that was it. Just providing my two cents that this also sounds to me like a Threads issue. Starting with v2.6, thread went from being allocated dynamically to a static pool. So if you were running some variant of 2.5 or lower and then upgraded to the latest (2.7 whatever), it is likely a Threads problem, as the default is pretty low.

I'm not sure abount Pound 2.7, but I think the 2.6 version uses a pool of a fixed number of threads, based on your configuration; the default value could be too low for your increased load.
