#389876 — Bug#1103296: systemd: Caught <ABRT> from our own process

[Multipart message — attachments visible in raw view] — view raw

Package: systemd
Version: 252.36-1~deb12u1
Severity: grave

Since upgrading from 252.33-1~deb12u1, we have systemd fall over with
| systemd[1]: Caught <ABRT> from our own process.
| systemd[1]: Caught <ABRT>, dumped core as pid 797507.
| systemd[1]: Freezing execution.

rendering the system near unusable as any following systemd interactions
time out:

| dbus-daemon[1135]: [system] Failed to activate service 'org.freedesktop.systemd1': timed out (service_start_timeout=25000ms)

This happens on two of our systems.

A contributing factor might be that we have a socket activated service
that runs only for a tiny amount of time but gets triggered at a rate of
about 10/sec:

| [Socket]
| ListenStream=13
| Accept=true

| [Service]
| DynamicUser=true
| ProtectHome=true
| PrivateUsers=true
| StandardOutput=socket
| ExecStart=-/usr/bin/date

Would you be able to provide the core file too?
