Hi, currently I run an OM 4.0.10 server with a pretty default configuration, using
# java -version openjdk version "1.8.0_242" OpenJDK Runtime Environment (build 1.8.0_242-8u242-b08-0ubuntu3~16.04-b08) OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode) on Ubuntu 16.04 (default values for file handles limits). I integrated OM with a web app made in PHP with the Yii framework, using the SOAP API. I use this library: https://github.com/hakeem23/open-meetings-soap The server is on AWS, being a c4d.4xlarge instance, with htop reporting 16 cores. CPU usage is reported by AWS to be around 50%, with a system load maxing up at the 5-7 range reported by htop. The thing is that as many as 100 users try to list rooms or connect to the server at a given time. I'm having several problems with the service, the main one being that the users sometimes can not get the room hashes or enter a room. Given the flow of the process, my best guess is that the library can not login to the OM server. The errors in the output are like these, I think (I'm not sure if these are the cause of the problem): DEBUG 03-25 11:44:24.577 o.a.o.d.u.AuthLevelUtil:42 [0.0-5453-exec-7] - Level Admin :: [DENIED] DEBUG 03-25 11:44:24.632 o.a.o.d.u.AuthLevelUtil:42 [0.0-5453-exec-7] - Level Admin :: [DENIED] DEBUG 03-25 11:44:24.633 o.a.o.d.u.AuthLevelUtil:42 [0.0-5453-exec-7] - Level GroupAdmin :: [DENIED] DEBUG 03-25 11:44:24.642 o.a.o.d.u.AuthLevelUtil:42 [0.0-5453-exec-7] - Level Admin :: [DENIED] DEBUG 03-25 11:44:24.642 o.a.o.d.u.AuthLevelUtil:42 [0.0-5453-exec-7] - Level Admin :: [DENIED] and so on. But I'm unsure if this is the error which causes a cascade exceptions which render the web app unable to get the room hashes and so (those process relay on being loged in, anyway). The thing is, the SOAP library currently does the login process from the app, using and user "admin" with SOAP and ADMIN level credentials. And the problem is intermitent. Do you consider that my guess is right? Is there a limit on "logins" at any given time? If so, can it be increased? Does the version of java affect? Any other ideas are welcome. Regards, Rodolfo.
