Process logs
WebSphere Application Server processes contain two output streams that are accessible to native code running in the process:
- profile_root/logs/server/native_stderr.log
- profile_root/logs/server/native_stdout.log
Text is written to the streams by both the JVM and by native modules...
- .dlls
- .exes
- UNIX libraries
- Other modules
If you turn on the debugging service or verbose Java logging, the size of the native_stderr.log and native_stdout.log files increase in size with each restart of the application server. This situation can cause application server crashes especially on Linux operating systems where you might have a 2 gigabyte maximum file size. To prevent this problem, consider redirecting the Java exceptions and verbose garbage page to other files.
We can increase the maximum file size beyond the 2 gigabyte file size limit if you enable Large File Support (LFS).
