Yes, Philip.
I saw your mail. Thanks for the update.
Couple of points:
Since we don't have config to try to repro and as per you observation, it's an intermittent behaviour, So we will do the debugging offline over email, the way we did for tar.
As issue is also vanishing over time, so issue might not be within this package but behaviour is impacted by external entity like Pure storage server. Just a guess as of now.
If you see, tcsh tool-box package is release on 2017, so from when your team is using this package and any idea why we didn't observe over past years if it is being used
It's possible that issue exists from day 1 or any env change in your infra is causing this. Any change in infra if you can narrow down?
We will start with truss output only as starting point.
Please collect truss output at the time of working case and failure case and share these details along with any input on above point over email.
Let me go through tcsh code once and understand the code flow for the parsing of globbing pattern.
Thanks
Ranjit
