log4j RollingFileAppender hangs in WinNTFileSystem.getBooleanAttributes

Question

All,

We have been using log4j's RollingFileAppender for quite a while using a properties file, with no issues. Recently, we had a requirement for a rolling log that needed to not use a properties file, but to be programmatically configure. No problems getting that coded. Now, we are experiencing hangs in WinNTFileSystem.getBooleanAttributes when log4j attempts to roll the newly added log file. getBooleanAttributes is called as part of the call for File.exists.

I can't come up with a reason why this should be so. Has anyone experienced this? Have any suggestions? At this point, all I can think to do is to write my own roller.

Thanks, Todd

Answer 1

It appears that the index used for the maximum index to which the files can roll was too large. Since we didn't really want a limit, MAX_INTEGER was used. Now, the maximum index is computed based upon total disc size allowed and is much smaller than MAX_INTEGER.
