[HELP] Mage character is freezing

Hello!

I have a problem on my server and i really checked anything and currently don't know what to do...

When i taking any mage profession char (main or subskill) and going in any location and attacking any mob my character is freezing. It stops moving, chatting and can't do anything but i can see that other players acting around, killing mobs etc. And i can rotate camera.

I tcpdump'ed network packets and found that game client is only receiving and sending world update packets but not SENDING the packets when i trying to do any action.

I think that this is not server problem but maybe game client is freezing after some bad server packet? Why only mage chars, never warriors even if i killing mobs with mage skills? What i need to check next?

Updating symptoms:

One of the players with Cardinal prophecy freezed when he healed another player.

So, there is a problem with any mage chars when they using any skills on any target... bad...

[goncafa]

Many many players on my server have been reported the same issue many times.

I always thinks the problem is no on server, but now i can see that im not the only one with this problem.

[Starter]

Confirm this problem also. Maybe its some sort of stuck in the character skill queue, dunno. Im having a bigger issue with character skills what makes the server even crash randomly but yet no answer from devs if its me or a general l2j issue atm.

[MELERIX]

probably is realted with floodprotector, is players fault anyway.

LOL? Ofc its players fault to play and suddenly stuck.. Huh? This is defineteley NOT a players fault, its a bug in l2j and exists quite long now.

Updating symptoms (i was mistaken in some points in the first message):

Freezed char CAN chat, see what happening around, use map, open inventory.
Freezed char CAN'T move, use any action or skill or potion from quick bar, quit or relogin.

Inventory of freezed char looks like not active (transparent) but i can scroll it up and down, not tried to do any other actions in it, sorry.

Sometime it's unfreezing when you perform the same action many times in a row, one time i just pressed F1 (attack with Dead Spike skill at that moment), second time i clicked at one point on the ground with the mouse.

Today we found that this happening after 70lvl of character, we not sure at 100% cause we have only one report about level, need testing. Today we also leveled up one Sorcerer from 77 to 85 lvl with no problems or freezes but our 70-72lvl Necromancer freezing in 5 minutes.

That's all that me and my friends has found today, thank you guys for information, i think i know what i will test next and tell you about results.

[zatei]

Our Sourcerer also freezed on 85lvl

Tested inventory, it looks like not active and functioning good, i can move items, etc.
Opened map, not active like inventory but works.

[Origami]

It would probably happen because of:

• using many times patched client
• using some third-party protectors like REMOVED or REMOVED which could probably not be fully compatible with your client and/or server

First of all I would disable all the stuff and use clean official client. Would you?

[UnAfraid]

just increase values of packet executor's config in General.properties

Already patching new client, don't use any guard at now.

2 UnAfraid
Can you please tell us what params we need to change?

[Starter]

just increase values of packet executor's config in General.properties

The default values for things like this and some more related packet sending/recieve should be a bit reworked anyway since I guess that the default values are set a bit too low. If you start a fresh server nowadays players will randomly disconnect without a particular reason because of that low settings.

[zatei]

I have tuned this settings but nothing changed.

Today we tested some mage chars and found that Necromancer class is most buggy. We can freeze Necro char in 2 minutes while other mage chars freeze twenty times less frequently.

So, how to fix it?

[Origami]

Guess nobody can help you unless you provide the algorithm how to reproduce this bug.
I've just created a new Necro using clean installation and haven't found any strange things.
Have you tried to do the same?
PS! Look, is it really necessary to ask you to provide the community all of the information about your installation, hardware, OS, java version and etc.? May be you could guess that this info can help?

2 Origami
Don't tried on clean install, cause this is not solve the problem with my non-clean install. Anyway not only me have this problem and i think that we don't need to spend time on very very abstract tests with clean installs or with clean clients, i think we just need to work together to find what equals in our server configs or mods.

At the moment I am studying a problem and try to reproduce it and that's what i found 15 minutes ago:
When Necro is attacking mob i can see packets and actions in stdout.log and in java.log (with all debug configs of course). There is no error in all logs when char is freezing but i watched the logs an hour in a row and see how the different packages are alternated with each other. When character is freezing i can see a group of 10 similar packages "Spawn protection for player... etc." packets in stdout.log. This never happening when all ok, only when char freezes up.

I will paste part of log to you next time when i catch this bug.
