@Tails I use the 100% standard Minecraft downloaded from Minecraft.net when this issue appears. However, i DID try to add unofficial plugins (Optifine) to resolve the issue, without success. |

I'm still experiencing this in unmodified 1.4.5 client+server. Not sure why the bug was closed. |

This ticket is invalid as it relates to a modded or 3rd party client/server.

I have this problem as well. It appears to be related to sounds loading. It seems to only be certain sounds (cow, minecart, ladder, a few step sounds, and especially a certain ambient sound that plays occasionally), but the game freezes for a couple seconds right before/while playing them. Pressing escape to pause the game and then unpausing it immediately fixes the lag (and causes the sound to stop). |

I have definitely noticed a new and distinctive freeze lasting about a second and happening every few minutes. I just noticed it in 1.4.3 but it may have also been in 1.4.2. It's not much older than that though. It happens in both the Overworld and the Nether, and I can't correlate it with any particular activity or game event. I'll let you know if I figure anything else out. |

Regarding message posted: 27/Oct/12 by me. I still have the issue. but not as frequently as before. It defiantly have something related with "memory release" or allocation. |

No i dont think its texture packs that cause this. because i only use the vanilla textures. nothing else. |

I've discovered that going 100% vanilla fixes the problem... I think there's something wrong with how people make texture packs.... as trying several different packs reproduced the problem, but vanilla always works fine. Talking version 1.4.2 |

For information: Update: I have reinstalled java 1.7.0u9, (used tar.gz instead of rpm), manually updated lwjgl (2.8.4)), changed the "driver" and "device" options in /etc/openal/alsoft.conf, and added the following command line options to java "-XX:+UseG1GC -XX:MaxGCPauseMillis=100". i'll test more tomorrow to confirm that the issue has been resolved. |

Tested with optifine 1.4.2, did not solve the issue. However: |

Tried downgrading java to version 1.7.0_u7, did not fix the problem. |

Yes, I have noticed a "freeze" when any sound file initiates. Turning off the music helps immensely with that aspect of our problem. I hope this info helps a little, trying to think of everything related to this. (BTW... I have given java up to 12gb of RAM... makes absolutely no difference) |

will try to update ljwgl. and give feedback if that solves the problem. |

I have this issue too... however for some unknown reason, my system recovers from the issue before the CPU usage hits 100%... on the other hand, the "lag" spikes come quite often. |
