dtlogin cores on me

Like making the early morining cup of tea I power my home machine on every day to read my emails. I usually come back to a dtlogin screen. But today it is different. No dtlogin but a

Nov 22 07:32:30 miaplacidus genunix: [ID 603404 kern.notice] NOTICE: core_log: dtlogin[300] core dumped: /var/cores/core.0.dtlogin.1101108749

On my screen. I login as root and as I have setup coreadm I know where the core file will be. A quick pstack on it does not reveal anything that points to anything obvious:

If I was running Solaris10 I am sure greenline would have restarted dtlogin but thats another story. So I run dtlogin's init.d script and I can now login.

Using the stack from pstack I poke about in Sunsolve and eventually find a bug id that matches the stack. I then use the bugid in the patch descriptions section of Sunsolve and find the patch to resolve this issue. It is fairly new and only just fixed in the latest build of Solaris10 too. Download from our server and that should be the end of it.

Last chance for the Cutty Sark

The tea clipper Cutty Sark which is in Greenwich , London is in a sorry state. It has been in a dry dock for fifty years of its total age of one hundred and thirty five and the site will have to close in 2007 unless something is done. The iron ribs holding the ship together have corroded badly.

The architects Grimshaws have a plan to restore the ship and enclose it in a glass bubble accordingly to the Sunday Times article last week. The cost to conserve the ship is about half of the total project cost of twenty five million pounds.

The cover over the ship will be an inflatable enclosure using the Tensarity structural system of rigid pneumatic beams. It will look a bit like this when it is done. The Times says the glass enclosure looks a bit like a giant Nelson's hat. It will be interesting if the project gets off the ground.
