More segfaults,on linux running 5.10.45 client.

Apparently there was a problem with the network connection and the client kept trying to reconnect.

All tasks whose results were about to be sent were marked with "compute error", for example: http://boinc.bakerlab.org/rosetta/result.php?resultid=162637592

I hope this helps.

Output of dmesg:

Post:
I get a crash when I detach from the project.
I'm not sure if this is a minirosetta bug.
Log messages seem to show that minirosetta was running when the crash occurred.

It is quite possible (and logical IMO) that the client forcibly terminates all related processes upon detach. Otherwise it could not clean up client_state.xml, slots/ and projects/.

I'm new to BOINC so I don't know how the detach operation is handled.

I don't use the gui manager and boinc_client appears to be the only BOINC related process running:

$ ps -e | grep boinc
6279 ? 00:00:05 boinc_client

Anyway killing related processes should not generate segmentation faults, so it's clearly an error in boinc_client.
I don't know if it has anything to do with minirosetta though.
