Theli v3 under Fedora- no RAM assigned

[maren551]

Hi Mischa, I just managed to install Theli v3 under Fedora FC 34, but as soon as I start I run into memory problems. In the Gui display the assigned RAM is always listed with 0%(28MB), independent on whether I assign minimum memory usage or a specific value. I actually have 8GB available. The size of the HDD is recognized correctly and also that there is only 1 CPU. But RAM is wrong. I can actually start the calibration task, but after the DARKS and some FLATs (FourStar) Theli crashes with a core dump and: QSocketNotifier: Can only be used with threads started with QThread.

I admit I have no idea what that message means, but there is obviously something wrong with the RAM assignment. Is there a possibility to check how Theli detects RAM?

Hi Maren,

THELI runs the following command on linux to query the available RAM:

awk '/MemTotal/ { print $2 }' /proc/meminfo

Can you run this command and let me know the result? Also, send me the your /proc/meminfo' by email to schirmer(at)mpia.de

Hi Mischa, sorry for the delay- now that we can start at the 2p2 again, we have to give the students a lecture that needed to be prepared. Anyway- I checked, the awk '/MemTotal/ { print $2 }' /proc/meminfo command gives me a 8020232 result. That agrees with the content of the meminfo file. It's attached.

This is not my usual work laptop, which still runs the old Theli v2 and has more RAM (16 GB). But before I upgrade that one I want to check whether I can get Theli v3 to work under Fedora. Using the old Theli is still better than not using any.
