I = am proficient in using docker on Linux. First, I tried to get the image to run inside my Kali Linux VM - it started, did not produce any errors, but the process kept running at 100% CPU. The same happened on another fresh Debian= 13 VM. This was on my FreeBSD 15.0-RELEASE host (p2) with a AMD Ryzen 7 3700X 8-Co= re Processor and 64GB of ECC-RAM. I was suspicious and tried another vm on my small server, FreeBSD 15.0-RELEASE (p2) with a Intel(R) Atom(TM) CPU C3558 @ 2.20GHz (2200.21-MHz K8-class CPU) and 32GB ECC-RAM. The same behaviour. It= did not have an issue when using a Linux notebook without virtualization, so I = dug deeper. Then, I installed Debian 13 on my oldish HP Z440 Workstation with a Intel(R) Xeon(R) CPU E5-1630 v4 @ 3.70GHz (3691.66-MHz K8-class CPU) and 32GB ECC-RA= M. I used KVM to install a virtual machine (Debian 13) and ran mssql server insi= de that VM - no problem, even with a docker volume it worked as it should.=20 I then installed on the same HP Z440 Workstation on a different disk a fresh version of FreeBSD 15.0-RELEASE (p2) and with vm-bhyve I created a Debian L= inux VM (Debian 13). I installed the exact same packages as in the Debian 13 VM = from the Z440 Linux host. Here, the mssql process again went to 100% CPU and it = did not work. On a second VM, I tried the same, but with nvme as storage and e1= 000 as network interface, however, this did not change the behaviour. --=20 You are receiving this mail because: You are the assignee for the bug.=
