Very large hs_err_pid files are found in probe directories. They can be 1.5-2 gigabytes in various size. Are these files needed? What are they used for?
Whenever a java probe is crashed, an error log file is generated. The file is named as hs_err_pid<pid>.log, where <pid> is the process id of the process.
These files are only memory dumps. If there are problems with the probe crashing and creating these file frequently, a support case can be opened to determine the cause of the crash.
If there don't appear to be any problems with the probe and the files are old, they can safely be removed/deleted.
