Crash every 20 mins posted log

Launcher/pack Version: launcher 0.5.4.9/ pack technic 6.1.1l1.2.3 latest

Operating System: Windows vista 32-bit

Version of Java: Version 6 update 31

Description of Problem: So I've been playing technic pack for about a month now and lately the game has been crashing every 20 minutes. Basically i'll be playing and get a couple of lag spikes and then eventually I'll get a really long lag spike followed by the saving chunks screen and then a blank white screen, which i have to close manually to close it.

Error Messages:N/A

Well i think i know what the problem is, Optifine auto saves every 20 min by default. You might need to disable the Optifine and those lag spikes for me are fix when i put the render distance to short or normal. Hope this helps.

I'm kind of hesitant to disable optifine due to the fact that normally i can't play on normal rendering distance without lag, but with optifine installed everything runs a lot smoother and i can actually run it on normal rendering distance.

Would it be fine to post another error log to a different problem in this same topic or should i make a new one? Edit: never mind i googled my other problem which was with nei crashed whenever i look at a ic2 recipe. For some reason i didn't think of googling that.
