Mergesegs error

[Emmanuel <jo...@gmail.com>]

I try to merge 2 segments into 1. I've a cluster of 4 machine using hadoop
13.1 and the last trunk of nutch.
Every time i start my merge I've got the following error:
2007-10-03 22:06:28,272 INFO  mapred.TaskInProgress - Error from

I've increase the memory but it doesn't seems to change anything to my pb.
This error appears immediatly at the beginning of the process.

Do you experinced the same issue ?
Does anybody use mergesegs ?

Thanks in advance for your help
