problem to run x11vnc after upgrading system 7.7 --> 7.8

[rsykora]

Dear list,


after upgrading to OpenBSD 7.8 I seem to be unable
to launch x11vnc on it, the last lines it spits are

23/10/2025 16:15:05 shmget(scanline) failed.
23/10/2025 16:15:05 shmget: No space left on device

and I do not understand what they mean (ie., on what
device there is no space?).

Please, has anybody seen the same? What could be
the reason / solution?  


Thanks
Ruda
