I saw something similar with telnet sessions, not phantoms a few years
ago.
Also HP, but UV 9.6.2.6, HPUX 11, August 2002.
I hit it with PORT.STATUS...LAYER.STACK but I don't think I've hit it
anywhere else. At least I've never pinned it.
It happened when I was trying to collect stats on what we spent our time
on. I ran a job that repeatedly executed PORT.STATUS LAYER.STACK
(consistent with what Asvin says) and telnet sessions began hanging
right & left.
It was only when I used the LAYER.STACK option and I never saw a problem
with phantoms, although several were running, only telnet. I did not
see the ":nanosleep: Interrupted system call" error message.
10.1.14 release notes says:
Issue 7659
If one UniVerse process was executing a SELECT statement
against a file, and a different UniVerse process was
executing the PORT.STATUS command, the process selecting
the file may have received an error message similar to
the following:
"nanosleep: Interrupted system call"
This problem was unique to the HP platform and has been fixed.
There are 4 other notes that mention PORT.STATUS.
I did not recognize 7659 as my issue, but reading both of your posts, it
looks like maybe it is.
I am at UV 10.0.16 at present.
