https://answers.axonivy.com/questions/2508/ivy-log-files-are-empty-when-accessed-through-an-upstream-server<p>Hello everybody</p> <p>We got Ivy running on a windows server. A few weeks ago, we added an upstream Linux Apache Server which connects via AJP. When the Ivy application is accessed through this Linux server, the log files don’t get written anymore. The log files are generated every day but they are just empty. Also generated files with Java (e.g. Excel-Files) are damaged and can’t be read correctly. If we access the application locally through http, the log file gets written and the files can be generated and read.</p> <p>Could someone please help us figure out why these logs are turning out empty and how to fix it? Thanks in advance</p> <p>Marco</p>enFri, 24 Mar 2017 16:00:49 -0400https://answers.axonivy.com/questions/2508/ivy-log-files-are-empty-when-accessed-through-an-upstream-server#2532<p>We decided to update the IvyServer to 6.5 next week and will do some testing then.</p>Marco KlauenböschFri, 24 Mar 2017 16:00:49 -0400https://answers.axonivy.com/questions/2508/ivy-log-files-are-empty-when-accessed-through-an-upstream-server#2532https://answers.axonivy.com/questions/2508/ivy-log-files-are-empty-when-accessed-through-an-upstream-server#2523<p>Probably you are using 5.1.7 instead of 5.1.17. We recommend to upgrade to the newest bug fix release 5.1.11.</p> <p>At the moment I think it could also be a general problem with AJP/Apache/Tomcat communication. Internally IVY starts a Tomcat. We should try to isolate the problem. Could you try to use another Apache Server? Maybe you can install one on a Windows Server?</p>Alex SuterThu, 23 Mar 2017 16:52:17 -0400https://answers.axonivy.com/questions/2508/ivy-log-files-are-empty-when-accessed-through-an-upstream-server#2523https://answers.axonivy.com/questions/2508/ivy-log-files-are-empty-when-accessed-through-an-upstream-server#2517<p>Ivy 5.17 / Apache 2.46 on CentOS Linux.
