darkphan Posted March 14, 2014 Share Posted March 14, 2014 There appears to be a memory leak that causes our server to crash after an extended period of time. I have tried to schedule restarts when nobody is on to work around the problem (which is pretty rare, this is a fun pack and the folks on the server love to play it, heh). For those that will suggest "just give it more RAM",that is not the issue, we have a 5gb server, and, as you can tell from the included crash logs, that is being specified in the java start up parameters. http://pastebin.com/jTdPZ8exhttp://pastebin.com/TuBrPnj9http://pastebin.com/TA8fkZNz Link to comment Share on other sites More sharing options...
GenPage Posted March 14, 2014 Share Posted March 14, 2014 In two of your crash reports, It appears that ProjectRed is causing your memory leak. I am going to assume the other one is caused by the mod but happened to trip a vanilla method when space ran out. at mrtjp.projectred.transportation.TableUpdateThread$.add(routingthreads.scala:14) I would suggest considering removing the mod, and reporting the issue to the mod author. Sounds like they aren't properly cleaning up their Objects Link to comment Share on other sites More sharing options...
GenPage Posted March 14, 2014 Share Posted March 14, 2014 Also your -Xms setting should always be half of your max -Xmx. Its bad practice to force it to allocate the full 5GB. Set the minimum to hlaf and if it needs it to, it has the space to grow. Link to comment Share on other sites More sharing options...
TheMaestro42 Posted March 14, 2014 Share Posted March 14, 2014 Wouldn't those errors just indicated that Project Red was trying to acquire more heap memory at the time, rather than saying the mod itself has a memory leak? I have a small server with similar issues that will run out of memory after a couple days of uptime (Even with nobody logging in) also running Linux and the oracle Java VM. My problems didn't start showing up until either 1.0.8 or 1.0.9 I didn't have the issue with 1.0.5, so I wonder if it's one of the two new mods added around then, or an updated mod.

GenPage Posted March 14, 2014 Share Posted March 14, 2014 Thats what a memory leak is, when you allocate object references without properly dealing with after they are no longer needed. They just sit and use up space instead of being properly garbage collected. We've noticed that ProjectRed has been having some issues lately so we've been keeping our eye on it.
