Linux VS AIX. Panic Can open Smat.

[John Hamilton]

Ok I have to convert from AIX to Linux.
The problem is that occasionally  when starting the process it panics with can’t open the Smat file.   Has anyone else had this problem ?

Running
Cloverleaf 20.1.1.
RedHat Kernel Release:
Linux 4.18.0-305.3.1.el8_4.x86_64 x86_64

The only way to get it started is to do the whole shutdown region cleanup with removing the MonitorShememory, rdm.taf and database cleanup.
Anyone else having this problem>
I have set tall the file limits to match or exceed what I had on AIX.

I am able to open the smat files in the GUI so they are there and have data.

Snip of the error.

Have you tried running lsof to see if there’s a process accessing the file? Are there lock files that need to be removed?

[John Hamilton]

Not yet as it is working right now.  I will when it fails again.

Started looking at this with John (OP).  Noticed that the “current working directory” for a similar error showed up as “/proc”, which is incorrect.  The smatdb files are not in /proc,. should never be in /proc.  Hence the “errno 2” of file not found, etc.

Any indications why one of these would try to startup with “current working directory” as /proc?
