System working perfectly until I run the following and the system freezes :
rclone sync --log-level INFO --log-file /home/foo/bar/rclone.log /home/foo/bar/fee/ fofum:bucket
Once that happens, the freeze, I cannot interract with rclone in any way or else it freezes the system. I can run rclone config, that is it. If I run rclone ls fofum:bucket system freezes. Login under a different user, run rclone config, everything works perfectly, I can use rclone ls to list the contents of the bucket without errors. Run the rclone sync command above and system freezes, that user cannot use rclone anymore.
If I create a new system, install nothing but rclone and run the same command I get the same results.
System is a VM on an ESXi 6.5 system, allocated 16GB RAM, 64GB Disk, 4vCPU. System is dedicated to running scripts. Mostly Bash and Python scripts that move and manipulate data, run reports, and similar. Nothing unusual about the system at all. Ubuntu 18.04.x server with most of the utilities you would expect for running various Bash and Python scripts, Libreoffice headless, and mysql-client. System was running Perfectly. System is only a few months old, fresh install when migrating from a physical system to a VM. Tried it on a different ESXi host, new VM, same issue.
Contents of /home/foo/bar/fee/ is approximately 120 files in different directories, total around 200MB, nothing but PDF files.
I'm not new to Linux, been doing Unix/Linux Sysadmin for around 30 years. Never seen this before. Checked all the usual logs, including the ESXi logs, absolutely nothing unusual. Bizarre.
Anyone seen anything similar?
