Xiao,
there is definitively something wrong with your linux machine and the
way to handle threads. The threading module seems to cause the memory
issue... I'll make a non-threaded version of the code so you can test.
I'll send it to the list later this afternoon !
Cheers,
Thomas

edit s01scan_archive.py and add this line
print source
before
data = read(source, quality=False)
that should be at Line72.
and send the output,

http://mailman-as.oma.be/mailman/listinfo/msnoise I put my SDS data files in /home/msnoise/SDS
directory. In table config, I set value of data_folder is /home/msnoise/SDS, value of
data_structure is SDS, and value of export_format is MSEED.
This looks OK. Do you
have anything else than mseed files in the folders ?
