Problem Can't connect to server, have to re-install mods

[PhilHibbs]

Three times now in the last few months, I've had "Can't reach server" trying to connect to my Direwolf20 server. It's hosted by a commercial provider, Veoserv, and I've got a ticket open with them but I thought I'd try here to see if anyone can think of anything.

The solution that Veoserv keep giving me is, "Shut down the server, delete the 'config', 'mods', and 'coremods' folders, re-install the pack using the mod control panel, and start up again". It works, and only takes a couple of minutes, but it's a nuisance to have to keep doing that, and I might not be availabe to do that all the time if a friend is using the server.

Any ideas why this keeps happening?

2013-05-01 22:38:31 [SEVERE] This crash report has been saved to: /home/tcagame/PhilH/1969/./crash-reports/crash-2013-05-01_22.38.31-server.txt

So, is Steve's Carts to blame? Or is it a Redpower timer? I've been meaning to replace those with a computer and a bank of wireless transmitters anyway.
This time a simple server bounce fixed it. No need to delete and re-install this time.

Hm, this is odd. I have no Quartz or Quartz Dust any more. I'm sure I had some a couple of weeks back. And I can't pick any in NEI, I get "No such item".

I've found out what this is! It's the Deployers that I'm using to grow my trees with bonemeal. If one of them deploys while the cart is in front of it, the cart thinks a player is opening up the GUI. The first time it happens is ok, but if it happens a second time then the cart tries to open the GUI while it's already open the server crashes.

I've now rigged up the deployers to fire when the cart goes over a Detector Rail, so it shouldn't happen again.

Oh, and the Quartz problem was because the server pack was out of date. That was Veoserv's fault.
