/p4/hms/tmp/ has lots of rcmd.* files.
After 400+ days or running HMS, we have thousands of rcmd.* files in /p4/hms/tmp/ .
There should be either a cron job to clean these up, or it could be handled as an additional rcmd (insert ironic emoji). If these need to be kept for debugging, I'd think a week's or at most a month's worth of files would suffice.
In the interim, I'm implementing a cron job on each HMS-managed host, using find to select files older than N days and removing them.
