<div dir="ltr">We have a fairly high-volume (28m+ messages/day) application that works, essentially, as a pub-sub for many internal and external applications. We are experiencing an issue under load where and subscribers that are using ssl are experiencing a significant slowness in delivery. When we restart the server we begin watching the processes in our application and we can, very reliably and fairly quickly, see the ssl_manager_sup process message queue start increasing in size. As this happens, all messages for those subscribers with ssl endpoints begin to back-up and delivery slows to a near halt.<div>
<br></div><div>It appears that ssl is a bit of a known issue within erlang. Or, at least, a tricky use-case to perfect. Are there any known issues that we can address in terms of configuration, best practices in setting-up ssl connections or anything else for that matter we can be doing to resolve this issue or more clearly identify the root cause? We're in active troubleshooting mode and doing what we can to dig deeper including dissecting the code to the kernel.</div>
