My brand new MicroOS container host seems to misbehave and fills the logs with messages that make zero sense.
The first one is about agetty:
Dec 30 08:56:04 mos.example.com agetty[1745]: could not get terminal name: -22
Dec 30 08:56:04 mos.example.com agetty[1745]: -: failed to get terminal attributes: Input/output error
I have thousands of entries like this.
The service is started automatically since the default kernel options have the ttyS0 enabled (Why, oh Why?). So, does anyone knows why we have these errors?
Also, what will happen if I change the default grub to NOT have these ttyS0 enabled? Will a new update bring back the ttyS0 in grub?
The second message is this:
Dec 30 08:56:13 mos.example.com irqbalance[1516]: Cannot change IRQ 57 affinity: Permission denied
Dec 30 08:56:13 mos.example.com irqbalance[1516]: IRQ 57 affinity is now unmanaged
I suppose I should not be very concerned since some bug reports and discussion in Red Hat’s bugzilla say that these messages are informational only, but I wanted to also check here.
