Hello,

We have a apache server running on CentOS 4.3

In this server, our access log is creating in our predefined directory. We need to filter the entries on run time from this log and push them to their related directory under www.

For example,

As this entry requests to a pdf file from Oatrs directory, we need to copy that to a seprate access log in Oatrs directory under www. We have implemented this by creating a filter script in perl using File::Tail perl module (got that from CPAN).

Every thing worked fine and we were getting log entries in to seprate access log for each directory.

However, suddenly the log files under www and its sub-directories messed up. These files were repeated with their old content. I mean, at same point log got double because the log was appeneded to itself due to unknown reason.

Our main access log file is fine.

We have checked with perl module, our script and everything which we can do but didn't find any reason for messing up.

Have a look into this. I know its not a common problem, but still, its a strange problem.

Thanks, Kirtimaan

Hi,
If the content is rewritten, it means that the writable buffer of your script has problem with loading new values from the original file, check it out, thanks

Thanks nayyares,

If the wriatable buffer is the problem, then can you tell me a way to reproduce the problem. As you wrote that there is something wrong with writable buffer of script, how I can re-create that situation on my local test system.

This way I will be able to fix the problem. Any other suggestion to prevent this also appericiated.

Thanks, Kirtimaan
