x264 encoding stalls before end without any error message

[nautilus7]

Hi, I've run into the same problem twice the last 2 days. I'm trying to encode "The usual Suspects" Blu-ray (MPEG-2) to 720p using x264 r1259.

I 'm using a nVidia GeForce 8400GS and Neuron2's NV tools to decode the stream.

The first time the encoding "stalled" during the 2nd pass, 30-40 frames before the end without any error message. Second time it stalled 250 frames before the end, but on the 1st pass.

The command line is the following:

C:\Encoding\x264>x264 --pass 1 --bitrate 4390 --b-adapt 2 --bframes 7 --ref 12 -
-deblock -3:-3 --partitions all --direct auto --me umh --merange 32 --subme 10 -
-aq-strength 1.0 --trellis 2 --psy-rd 0.8:0.2 --rc-lookahead 60 --no-fast-pskip
--level 4.1 "c:\encoding\input.avs" --output NUL --slow-firstpass
avis [info]: 1280x544 @ 23.98 fps (152585 frames)
x264 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 Cache64
x264 [info]: profile High, level 4.1
[99.8%] 152340/152585 frames, 1.41 fps, 4297.01 kb/s, eta 0:02:53

At this point nothing happens... CPU is @ 0%... Don't know if it's a decoding or encoding related problem. Any advice is welcome.

My system is win7 x64, 3GB ram, Core 2 Duo E6600, GeForce 8400GS. I'm using 32 bit version of all programs (x264, avisynth, etc.)
