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:
