Frédéric Delaporte updated LOG4NET-506: --------------------------------------- Description: Many applications run on the same server. Some are windows services running under "Local system" identity, others are IIS hosted web sites running under "Application pool" identity. All do log through {{RollingFileAppender}} to D:\Logs\ (value of {{file}} configuration node) to their own file log (filename specific to each application through {{datePattern}} configuration node). They log through {{AdoNetAppender}} too. Since having upgraded Log4Net from 1.2.13 to 1.2.15 on all services and some web sites, upgraded IIS web sites cease being able to log to D:\Logs\. SQL logs still work. Non upgraded web site are still able to log to D:\Logs\. The services start before the web sites. Stopping all services then restarting a web site allows it to log again in D:\Logs\. Restarting a second web site (having a different application pool) while the first is still running does not allow the second one to log again in D:\Logs\ (Application pool identity give different identity to each pool). Activating log4net debug trace on a web site, and comparing failure cases to working cases, yields following diff: {code:title=failing case debug trace} log4net:ERROR Could not create Appender [RollingLogFileAppender] of type [log4net.Appender.RollingFileAppender]. Reported error follows.
