web console not responding after graceful restart

[Clockwork]

As described in the title. It's a brand new server, debian lenny 64bit.

I'm using lsws 4.0.7.

p.s. if I wait some minutes it's working again.

This problem also only occurs if I use the web console to restart lsws.

I've just added a part of my error.log.

It could happen on a very busy server during graceful restart, the old server stop serving request for the admin console, while the new server process is not ready yet.

I'm just setting up this new server, this means there are not visitors on it

Maybe the best way to trouble shoot this is to PM me a temp root access to the test server. I could not reproduce it in our lab, must be something special in your environment.

You can try enable debug logging, we could not reproduce it in our lab. may need to check what happened on your server if possible.
