Salome takes a long time to start (4 ~ 5 min)

Posted by Sofiane KHELLADI at November 29. 2020

Dear all,

 

I use Salome 9.5.0 on Ubuntu 20.10, few days ago, maybe after a system update, Salome began to take a long long time to start ... 4 to 5 min.

 

Any idea please on what causes this problem and how to solve it?

 

Thanks by advance.

I don't currently have an Ubuntu 20 workstation at hand to see if I can reproduce the issue, thus It's pretty hard to get a diagnostic. Do you notice same slowness with other applications like e.g. Firefox  and what is your desktop manager ?

You might find some useful hints about what yo can check first at this discussion:

All other applications seem to work well.

Maybe one other observation, when salome runs (after a while), geometry module seems OK, but the mesh generation takes much longer than usual.

Searching Naming Service  + found in 0.1 seconds
Searching /Kernel/Session in Naming Service  +Warning, no type found for resource "localhost", using default value "single_machine"

I checked with an Ubuntu 20 workstation and did not manage to reproduce the issue with the universal distribution SALOME-9.5.0.

Thanks for testing Salome with ubuntu.

I tried to run Salome once again today, and it works...!!! I did nothing special, not even a system update... its a mystery.

The problem seems to be solved, thanks again.
