After fixing the "duplicate compression" problem, we're now encountering "imap-login: Error: proxy(USERNAME): connect(10.x.x.178, 993) failed: Cannot assign requested address (after 0 secs, local=10.x.x.100)" in the logs. We already tried raising the ulimit, the max number of open files. Once we reach about 25k connections, we're getting the error above... for all

...llations hitting CPU limits in proxies. The problem so far has always been related to getting enough outgoing sockets without errors, which is a server-wide problem. 2.2.29 has one tweak that hopefully helps with that. > Which would be? The delayed connection bit? Anyway, with a properly sized login_source_ips pool this shouldn't be an issue, I have 80k sessions (that's 160k connections total) per proxy server now and they are bored.
