Description

Hello,

Getting a strange silent crash after this update:

SECCOMP auid=4294967295 uid=0 gid=0 ses=4294967295 subj=unconfined pid=34271 comm="exe" exe="/usr/bin/runsc" sig=31 arch=c000003e syscall=9 compat=0 ip=0x483284 code=0x80000000

That is the only thing I get in the logs before I start seeing logs that namespaces are dismounting. It occurs about 180 seconds after my app starts. I'm currently running an early build of a 6.12 kernel.

Should I ptrace this?

Thank you

Steps to reproduce

Let me know if needed. I'm getting this from a Java app with proprietary data, so I can't directly share it quickly.

runsc version

20250714.0 from the Gvisor apt repo for Debian Bookworm

docker version (if using docker)

28.3.2 build 578ccf6 from Docker apt repo for Debian Bookworm

uname

6.12 kernel for virtual machines

runsc debug logs (if available)

I can provide a ptrace, though it would be a very large file. Please let me know if needed.
