Solved 2 times in a row same time at night, crash...

Been having an issue where my server is getting shut down, happened yesterday and today again about same time today as yesterday, not sure what would be eating up over a gig and a half of the free ram the server has, running with 2 gigs currently from our host, and not sure if this is being caused by another plugin but we added "McMMO" and "Quests" before this issues started, but We've had the plugins for about a week and this problem just started 2 days ago.

This is all i got from console on crash, minus all the plugins stopping:

The last lines says everything "Out of memory Perm gen space" you have to add perm gen space to your start server paramethers

Add this command to your server start paramethers -XX:MaxPermSize=256M

Happens to me sometimes, that means you need to load your server with more RAM. Also keep in mind when this happens, all of your map changes will be reversed!

 

I'm on a hosted 2 gig server, Started the day after I added McMMO and Orbfuscator, and we only have a half dozen players on at a time, view distance is 6, we were running on 1 gig before and Never had this issue.

so i'm going to run without orbfuscator a couple days, more of a Want then a Need plugin currently.

my players Love mcmmo =D would a player logging in with a glass ground resource pack version of Xray cheating possibly be causing it? like when they login and it has to cover their entire view with orbfuscator? because it's only happening when a player joins the server, not the same person each time fyi, but it is when a person logs in, it eats the ram and stops the server. Thanks for all the replies, I'll keep this updated as i narrow it down, Still feel free to shoot off ideas.

Note: server normally runs in the 500-800 mb range and typically never falls below 1gig of free space, so I'm thinking it has to be one of the 2 plugins we just added. always 20.0 tps except when reloading a plugin of course.

 

Found out it was a control panel setting, I'd go in detail but I would have to specify our host.

Basically, there was an option for loading the jar file as CUSTOM.jar which the host allows higher PermGen space.

so If your hosted and having this issue, Contact your Host's support, if your running from your own computer or have the option to set the amount of ram allocated then the above comments would be the fix for you =)
