Out of memory error?

I had left my server running for around 24 hours, and when I went to look at the console this is what I saw:

Any ideas as to why this happened? Could it be that I left the server running continuously for too long? Also, I am using 1.3.2 R1.0, if that makes a difference. Any help is appreciated

 

Could you provide us a plugin list?

 

Plugins (34): MultiInv (v3.1.4), MCBouncer (v1.3beta), WorldEdit (v5.4.2), NoCheatPlus (v3.7.3-b111), PermissionsBukkit (v2.0), Vault (v1.2.19-b248), LogBlockQuestioner (v0.02), PlotMe (v0.9), Multiverse-Core (v2.4-b527), LogBlock (v1.60), MobBountyReloaded (v291), LWC (v4.3.0 (b736-git-1b1150b1) (August 08, 2012)), WorldGuard (v5.5.3), boosCooldowns (v3.1.1), MineBackup (v5.9.4), SimpleJail (v2.0.3), ChatReplace (v1.3.0), Honeypot (v1.4.2.1), CraftBukkitUpToDate (v3.0.0), AntiXRay (v1.5.2), ZavAutoMessager (v1.9.1), Votifier (v1.9), iChat (v2.5.9), MultiHome (v0.15), PluginController (v0.7), Essentials (v2.9.4), EntityManager (v4.5.1), Fe (v0.4), EssentialsSpawn (v2.9.4), Multiverse-Portals (v2.4-b548), CreativeGates (v1.3.5), VanishNoPacket (v3.12.1), SignShop (v2.3.6)

 

I suspect those 2 plugins:
- MineBackup (v5.9.4)
- AntiXRay (v1.5.2)

I have difficulties to find that AntiXRay plugin, where did you get it from? (Version 1.5.2)
