Dear Dojo,
While taking a SLLogCollector package of a certain DataMiner Agent, I was surprised by the size of the produced package (1,9 GB) since I didn't take any memory dumps. From inspecting the package, I noticed that there were tons of files in C:\Skyline DataMiner\Logging\FormatterExceptions\w3wp for about 14 GB of data (uncompressed).
Does anybody know where these files are coming from? From an earlier question about the w3wp process I understood it is a process used by Dataminer for Web Apps.
But how come there would be >10K files in that logging folder for about 14 GB of data?
Can I safely remove them without any impact?
Where and why would these files be generated and how to prevent this in the future?
Thanks!
Hi Koen,
Starting from DataMiner 10.3.9, these files get created whenever an unexpected error occurs during serialization or deserialization. In the instances where there are thousands of files, it is typically the result of the DataMiner running without a database connection for some time, or running close to the memory limit and encountering many OutOfMemoryExceptions.
These files are generated by the process indicated by the folder name, w3wp is the IIS hosting process name used by the WebAPIs.
These files can safely be deleted.
There is currently no automatic cleanup for these.
