Hi, im new at l2jserver ive been using l2jfree for about 3 years but that project is dead and now ive migrated to l2jserver.
Im having some troubles with my server, yesterday there was about 300-350 characters online and everyone got stuck, they could chat, drop items, etc but they couldnt move, and sudenly the started to run vey fast to nowere, when they restart and relog they were in random places. This happened to the whole server. What could it be?. I was thinking that probably was my poor hard drives, but i had no problem with more than 700 characters online before so i dont know why could have that happened. I think that probably it could be because of the GB, because i probably have a bad JVM config. Thank you very much and sorry about my english, i hope you guys can help me.

heres my my.ini of mysql.

I'd suggest you raise your thread configuration rates. I'm not sure the standard rates are good for a 100+ populated machine.

It doesnt really have an explanation, so you might need to experiment a bit

What do you think about this thread config considering that my cpu is an Intel2Quad 9550:

hardware problems wouldnt explain players moving around by themselves lol, if the error affected all players, i belive it means its server's error.

If it only happen once, then its just devil's work, else this will need the eyes of the creators (developers =P)

It happened one time, but now it happens otherwise, randomly some people get stucked and when they re-enter they are in other places. Ive changed the thread config, if i have any new trouble i will report it here. I have about 400-450 chars online.

hardware problems could cause lag, crashes or even some broken data but, the bug you are talking about looks like something in the code =P hardware problem wouldnt magically stuck ppl then teleport them to random locations.

Tell me, when you say "random locations", how far from the initial location you are talking about? and players are moving to the same direction?

I will inform you this as soon as i talk with my users. About the first question, how far... not too far, but i will confirm this soon. They also inform that sometimes the player sudennly unstuck and start running really fast to a new location.

my best shot, is that your server is executing the walking procedure without client instruction, since you told me that the distance is not too far.

for the player, it might look like he is running fast but, thats just the server updating his position and forcing him to move where he "should". Still, this bug is very weird .-.

Yes its weird, i think it can probably be because the server is loosing the location packets somehow, because of a bad mysql config or bad gc config, what do you think


//offtopic question: is this variable set to high?

Code: Select all

# Maximum size for internal (in-memory) temporary tables. If a table# grows larger than this value, it is automatically converted to disk# based table This limitation is for a single table. There can be many# of them.tmp_table_size=768M
And this one should be 0 for l2jserver? i was told this should be 0 for l2jserver, but i cannot understound that could be logic..

Code: Select all

# Query cache is used to cache SELECT results and later return them# without actual executing the same query once again. Having the query# cache enabled may result in significant speed improvements, if your# have a lot of identical queries and rarely changing tables. See the# "Qcache_lowmem_prunes" status variable to check if the current value# is high enough for your load.# Note: In case your tables change very often or if your queries are# textually different every time, the query cache may result in a# slowdown instead of a performance improvement.query_cache_size=186M

Something strange is happening now. Some characters, not all of them, get stuck and after a while they start running to a random place. I have 600 characters online now counting offliners, could the sh1ti hard drive be the problem?

my cpu is always at 5%, or 10%, it has some 35%-40% pikes. Today ive discovered something, that probably is making the problem.

The error is happening at the same time this event runs: viewtopic.php?f=73&t=19807 (TvT rounds by SolidSnake). Maybe something in that code is making my server loose axis sync with some characters. I will test the server without the event. I will report the results asap.

I will try that, is that +java a typo error for -java or the (+) does change something?, if it does what it changes?. Just curious.
