This is usually due to Websphere scanning the dropins folder for
updates. z/OS doesn't have edge triggered kernel hooks like inotify on
Linux so has to use brute force. It's not just I/O it consumes a lot of CPU.
You can disable it in server.xml
<!-- Disable monitoring of files to reduce idle CPU -->
<applicationMonitor dropinsEnabled="false"
locationMonitoringEnabled="false" updateTrigger="mbean" pollingRate="10s"/>

How canI tell what it is doing? I expect most of these files are in the
zFS file system, but I dont know the best way of finding out what is going
on.
I do not have tools like Strobe or APA,and I am familiar with dumps etc
