RStudio Server: Error occurred during transmission

Monitoring the system with journalctl -f I get the following messages whenever a user tries to log on:

Apr 13 13:35:07 my_server kernel: rsession[22336]: segfault at 50 ip 00007f4c81a0fb8c sp 00007ffd1ec92070 error 4 in ld-2.26.so[7f4c81a03000+27000]
Apr 13 13:35:08 my_server kernel: rsession[22341]: segfault at 50 ip 00007f10451deb8c sp 00007ffec8acada0 error 4 in ld-2.26.so[7f10451d2000+27000]

Any hint on what may be the cause?

Thank you.
