Jan 22 13:24:54 redacted zfsd[886]: Disconnecting from devd. Jan 22 13:24:54 redacted zfsd[886]: ConnectToDevd: Connecting to devd. Jan 22 13:24:54 redacted zfsd[886]: Unable to connect to devd Jan 22 13:24:54 redacted zfsd[886]: Disconnecting from devd. When this happens, several other things happen: 1. the sshd server dies. Already-established sessions still run, but=20 the server itself stops and no new ssh connections can be made. 2. syslogd dies. so does exim, nginx, smartd, sshguard, pf I don't know where to start looking for reasons for this. Is it a known issue? In the meantime I've turned off zfsd as it's not really needed in this machine's context (headless, zfs on single disk), from what I can tell. --=20 J. --cN8/Qsv4xgEsS6SG Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAmHsFfUACgkQs8o7QhFz NAXSLQ//a6StY92eAnZH9yFn3Daqr0KSf3PhHM7y4LJqv5q8T2HNSVmZUst2EKaS IkFSozB9V5CY5qtV0RfRtcvdR+Pv2aN4zp7CuKYp91LGe+Q+gmNAf4D1UOkVnqvc bbCXHBNj22piXsqfpoCxKWLvNV5rqNbGSEPBkFz0y/z50m5hSPwcu9b8A/xY55WG /Ptd7zL1Lv+wZ91E31oPOe3jNHidwoSHah9otMBMhZuJkQXiaLi8c8vT+ChGPRW5 TO/2QKBnBfnNIxiOY1jYS46kSTH14W8snTHnjRRbrc8TCJ+5GRo5MlS0Y0DeXGoP QAh79vrGu3/NqnEcnE8OxMsbPiSpW+pjiyCKCJwKg4WzxUT2UbX8DRL1Dt+uhPjl UqaJ/mX9fvUFTLcIblPNlD5nEmPp9MOuEmXW0O634unN7HUX4BSH5wgljFgUAoSX o/9xN5SFgDbrz9Irns9vvKgJvpKXuGzJzvpEod/20DKThLV8FcFyDcTCNBKVD5PB 33shA+sR/CJTEPHaVa+bUJiuSU3+arO0T2HpcmtXIeivv/obpwrAI4Hev+Dki16e ml4jklzeCl64qdCrPsoXd3avOCv/FXhiQkMyhELRXtE3TPW+8weG45yKQqmjSftC pNgyDFDsNz+LZR/W8ENEeQmIwp372z31uMTk9lf+BssMgCP0yT0= =C4Fm -----END PGP SIGNATURE----- --cN8/Qsv4xgEsS6SG--
