    I noticed my server's memory usage for javaw (server task) starts at around 500mb and over 3-4 hours climbs past 1.8gb and I get a read time out...

    Linux DV051 2.6.35-30-generic #54-Ubuntu SMP Tue Jun 7 18:41:54 UTC 2011 x86_64 GNU/Linux
    java version "1.6.0_24"
    Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
    Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)

    CB Snapshot #953

    Have tried starting server with both, same problem
    Code:
    screen -S minecraft java -Xmx1536M -XX:ParallelGCThreads=2 -server -Xincgc -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:+AggressiveOpts -XX:+CMSParallelRemarkEnabled -XX:+DisableExplicitGC -XX:MaxGCPauseMillis=500 -XX:SurvivorRatio=16 -XX:TargetSurvivorRatio=90 -XX:+UseAdaptiveGCBoundary -XX:-UseGCOverheadLimit -Xnoclassgc -XX:UseSSE=3 -XX:PermSize=128m -XX:LargePageSizeInBytes=4m -jar craftbukkit-0.0.1-SNAPSHOT.jar nogui
    
    screen -S minecraft java -Xincgc -Xmx1536M -jar craftbukkit-0.0.1-SNAPSHOT.jar
    Remove all your plugins and try with just CraftBukkit. Does the error/problem still occur? working that... Takes anywhere from 2-5 hours before this starts to happen
    Memory usage gradually climbs upwards util it exceeds 1.7GB then crashes, regardless of players... Any one else have more info?

    Update your plugins: all up to date.

    Code:

    Why is this happening? disconnects all my players.... And server crashes, any one know?
    This didn't happen before 1.7.2

    Top results 12 minutes after server starts:
    Code:
      PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
    30232 some01    20   0 1987m 629m  10m S 33.3 20.9  12:30.18 java
    

    Top results after server has been up for 102 minutes, 10 players currently connected

    Code:
      PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
    16949 some01    20   0 2005m 1.2g 6844 S 59.0 40.8 102:01.65 java
    shortly after this, Terminal locks up, javaw Reaches 50-60% which is exceeding its limit for the startup script, then this:
    Code:
    07:01:51 [INFO] Read timed out
    07:01:51 [INFO] guy lost connection: disconnect.endOfStream

    then the server stops or closes its self.

    My server went from being EXTREMELY stable to the exact opposite. Minecraft now eats up more memory than I've even allowed it, bleeds into swap, and crashes. I can only keep the server up for about an hour and a half at a time now. WTF.

    EDIT: Just crashed after 56 minutes of up time. Process is using 65% of my server memory with 0% CPU usage. This is typical of what I see in htop every time it crashes. Same java run-time parameters as usual. This IS a 1.7 issue. Killing the hung process frees up over 4 gigs of memory.

    I'm having this same problem and I can't be around all the time to check if the server is still running. This is incredibly frustrating. I'm losing players because this keeps happening.

    I have moved from CB953 to CB961. I know this is not a recommended build but it is MUCH better.

    Still happens though, just takes longer :(

    I'm thinking I may have to reenable essentials' "reclaim memory on logout" feature. My run-time parameters just aren't cutting it anymore.

    Scratch what i said earlier. Not better. Essentials config didnt help either - worth a shot though...

    Two full days and not one decent answer. I've tried near everything.

    Bump in hopes that someone will help aswell. This problem started with the 1.7.2 update. Thread-5 has an exception. Same memory leak error in chunk generation. *shakes head* my users are screaming Fukkit Bukkit all over my website and whenever the server is restarted. Guys help please. :c

    Easier to wait it over until 1.7.3 come out so they don't have to update twice i guess...

    Have you tried any of the dev-builds higher than 953?
     
  17. Offline

    Legionarius

    I have tried all of them. Also 953 is out and there is no mention of any memory leak fixes. I hate to say it, but I don't think 1.73 will fix anything.

    I can substantiate this as well. Can anyone actually get in touch with a @Dinnerbone or another heavy hitter? This is a BIG deal.

    I also get the Read Timed Out error except it's really random of when it occurs. It's from 15 minutes to 10 hours.

    When Read Timed Out happens it sort of freezes. I cannot type in :'stop' at all. So I will just have to force exit the CMD by clicking the top-right 'X'

    When I get my server back on some of the people's inventories are WIPED! So I am getting a lot of complaints about it and it is difficult for me to just give them items EVERY time it crashes.


    1.7.3 using 953... I also had this with 1.7.2 using 953.

    People have and are going to ragequit if this continues... :c

    Big Red banner at the top reads: "Not getting any help? Try reading....."
    Its like the forum is trying to make me furious...

    But seriously, Can we at least get some confirmation that a member of the bukkit team has glanced at this? It's a real issue for a lot of people...

    I'm now in the process of upgrading my server from 4GB to 8GB, Adding a new CPU and Switching to Solid State Drives... If i continue to get these read time outs, will you believe that its a problem?

    Bukkits twitter is filled with adding new stuff... You guys do great work... but can we fix what's broken first?

    @Beldrama @Pulserock Please take a moment and fill out this short template, It will help us to have common factors between those who are crashing. if EVERY one was crashing it would be fixed by now...

    Switched to a new server, Upgraded to 8gb of ram, and still get these errors, It does however take, much, much longer...
    down to only 1 reboot every 18 hours or so...

    still sucks... but now i can sleep.

    I'm using an auto-restart plugin but the amount of time it takes to overflow the memory is unpredictable. Not to mention a 2hr restart might piss off a few ppl XD

    It would be nice if the bug/issue could just be resolved, a crontab isn't a solution thats a work around. Thank you for the suggestion.
    I could run my server for weeks without a reboot before 1.7.2...
    Changed my startup script again, maybe it will help...

    Runs for about 10-20 hours now, 17-30 players on at most times of the day.
    may try a crontab for reboots every 10 hours, until this is resolved

    Additional comments? Server will start out fine, then as the memory usage climbs, the console will begin displaying "[WARNING] Can't keep up! Did the system time change, or is the server overloaded?" This happens regardless of how many users are online. Once the memory usage reaches ~1.7GB the server will lock up and close itself; this normally happens after the server has been up for 2 hours.
     
  30. I'm not sure how.. but I seem have to fixed it for me..
    But the only things I remember doing were installing this plugin called RemoteToolKit. It's supposed to automatically bring your server back up after it crashes/receives a [SEVERE] warning. You can also configure it to automatically restart your server, auto-save, etc.

    But the other thing I did was uninstall BigBrother (it's supposed to have some bad memory leak right now), change my view-distance value in server.properties, and install a plugin called PerformanceTweeks.

    If anyone wants to try all these and see if it fixes your crashing problem, perhaps we could narrow it down to something..
