Re: [Hypercontent-users] H/C Error

Thanks Alex,

I wasn't sure I could delete the whole workflow-data directory.  I did
that as suggested and it's working without problems.

I'll make sure I use kill -15 in the future.

Cheers
Carl

HI Carl,
	The quickest and ugliest fix would be to stop the server, delete
the =20
"workflow-data" directory from that project, and restart.  Somewhere =20
in that directory some of the data is in an inconsistent state due to =20
the forced shutdown, and I can't seem to ssh in to track it down.  =20
Deleting the workflow data directory will wipe out all records of =20
past workflow activities (build, publish, etc), and will kill any =20
approval requests currently outstanding.    For many sites this isn't =20
a big deal.  If you don't want to lose those records, or if you have =20
time to explore further, I suggest you ssh into the server and look =20
beneath the workflow-data dir for files with 0 length, or any files =20
named "file.lock" which you can then remove.  Also, if you want to =20
zip up the repository from the command line and make it available to =20
me via some URL I might have more luck digging into it.

You're right that there's no shutdown script - if you're starting up =20
from the Ant script, just type "ctrl-c" in that window to do a =20
graceful exit or do a "kill -15" on the process.  If you deploy it =20
into a separate tomcat, you can use tomcat's shutdown script.

Cheers,
Alex
