Read timed out.. So sick of that!

Im getting sick of this kicking my players every time they play!... what can i do to stop it.

(Random thought can this be related to my router its behind? It is a WRT54GS with DD-WRT installed on it.)

Code:

Plugins:
Bioman
CCLogger
Citizens
Essentials
EssentialsChat
EssentialsSpawn
HideStream
mcMMO
PermissionsEx
ScriptBlock
SpoutEssentials
spoutplugin
tombstone
Vault
WorldEdit
WorldGuard

Edit: I removed spout essentials because of another reason and it still persists. So its not Spout Essentials.

 

Yes this can be essentials related start the server witthout
the following plugins:
Essentials
EssentialsChat
SpoutEssentials
EssentialsSpawn

 

This can be caused by a few things. Try without all plugins - this should stabilize your system to allow players to connect. If they are still getting kicked, yes, it could be your networking gear. Try replacing the router, replacing the NIC, or even replacing the cable. I wouldn't suggest using wireless.

 

I haven't disabled the Essentials plugins yet. As i assume that this has something to do with Bukkit. So i want to pursue that first. (I have read countless posts that say removing all the plugins didn't help anyway.) So i have a plan!

1. I'll Update to Java 7 (64bit) and see if it happens again. (Also updating java to 7 on 2 out of 8 users.)
2. I'll remove the router element and place the server directly behind an IP Device.
   (That should bypass any ports and firewalls.) (This is unwanted because the server is behind a dynamic-ip and it shuts down after inactivity. The router has DDNS setup to bypass a dynamic ip address.)
3. I'll update bukkit to the latest beta build (recommended if it shows up in time.)
4. I'll remove only the essentials plugins.
5. I'll remove all the plugins and test again.
6. Take it to the official bukkit error page.
7. Give up

I'll go in that order. If i reach 7 without removing the problem, then i'll blame Minecraft.
This seems weird, why would this start happening lately and not a year ago. I have had this server for more than a year.

Edit: as a side note installing java 7 64bit on my server has increased its performance by 25%. I'm noticing WAY less CPU usage and faster response times with various commands.

Edit: I also installed the Essentials Pre(2.9.2.2) for Bukkit 1.2.5 R1.0
Lets see if it persists after this. If it does i'll continue with step 2.

 

Maybe Essentials? Maybe not?
