Commands does work after some time

Hey everyone,

I got two problems since I update the server to 1.5.2 (CraftBukkit Beta Build (1.5.2-R0.1))

The first problem is that some commands (at this moment everything looks very random) stops working after a while, when the user types and press enter, no response from the server. The way to fix this, is that the user needs to type a wrong command, like /sadhiugh, then the right command again and is working perfectly after that. Initially I though that is essentials fault, but then commands like /spleef or /ar check stops working and these commands has nothing to do with essentials. I did a lag command to see if maybe lag is the cause, but looks alright:
[Server] INFO Nether "World_Nether": 421 chunks, 512 entities.
[Server] INFO World "World": 2,876 chunks, 1,759 entities.
[Server] INFO Free memory: 2,759 MB.
[Server] INFO Allocated memory: 5,545 MB.
[Server] INFO Maximum memory: 5,545 MB.
[Server] INFO Current TPS = 20.0
[Server] INFO Uptime: 14 hours 14 minutes 24 seconds

The second problem I have since update, is that Multicraft is showing me more players than there actually are on the server. Works perfectly before, but now after update, I see more players if I log in on Multicraft than are on the server. Not sure that this has anything to do with bukkit but since this happened the update, I am thinking it has something to do with this. Also if the server goes full on multicraft but not on the server, then the server will stop working until rebooted. This might be a host problem but I am not sure.

I did not post the plugin list because I don't think is need it, but if anyone think that there might be a plugin which cause this, please let me know and I will post the plugin list.

Thanks for your help

 

For problem two, that is most likely your server host. If you are using their 1.5.2 jar, then it adds more players because mine is fine. And I use multicraft, and other users don't have this problem. For problem one, I have had the same problem. Some plugins need to be updated or your commands don't work.

 

hmm, so what should I tell them to do in order to fix the second problem? Because I am using the .jar file provided by them.
