Versions of packages rsync suggests: ii openssh-client 1:7.9p1-10 ii openssh-server 1:7.9p1-10 -- no debconf information I am rsyncing files with the following command: /usr/bin/rsync --progress -avzse ssh 'user@host:/path/a/' '/path/b/' I have succesfully run this command on Debian Stretch before the upgrade. I updated to Debian Buster and now the system hangs when syncing large (400M) files using the above command. I have tried also a clean Buster installation but the problem persists. Initially I suspected this a hardware issue but I tested the disks with DD (on Buster) and even heavy load did not cause any issues. This problem seems to be related to rsync and large files. Rsync with small files works OK. Disabling AppArmor on Buster does not help. Symptoms: Aftert issuing the command, the rsync starts OK. Even large files are transferring OK at this point. After a while, the CPU load on the system goes to 100 % and the system becomes unresponsive. I am running the system on VMWare ESXi 6.7 U2 host and the system is using Broadcom 9440-8i RAID controller. If I switch from Buster to Stretch, everything works OK. Typically nothing can be seen in the dmesg but once I was able to capture the following: Jul 10 07:27:00 nasunas kernel: BUG: unable to handle kernel paging request at 000000f0416baec0 Jul 10 07:27:00 nasunas kernel: PGD 0 P4D 0 Jul 10 07:27:00 nasunas kernel: Oops: 0000 [#1] SMP PTI Jul 10 07:27:00 nasunas kernel: CPU: 0 PID: 1053 Comm: rsync Not tainted 4.19.0-5-amd64 #1 Debian 4.19.37-5 Jul 10 07:27:00 nasunas kernel: Hardware name: VMware, Inc.
