[Tilecache] seeding error

[SIMON MERCIER]

hi list

I trying to seed one of my WMS, it work fine but, the seed process alway(3 type of error) crash after 1 or 2 or 8 hours of seeding process.  My question, is there a way to force the process to bypass error or any idea of what is causing this problem?

Tilecache: version 2.04

My layer:
type=WMSLayer
url=http://spssoww5.sso.msp.gouv.qc.ca/cgi-bin/mapserv.exe?map=e:/ms4w/msp/wms/orthos_prive.map
extent_type=loose
levels=15
layers=Orthophotos
extension=jpeg
srs=EPSG:32198
metaTile=false
maxResolution=2530
bbox=-1257720,-155000, 1333000, 2435720

seed:
E:\ms4w\apps\tilecache\tilecache_seed.py "http://spssoww5d.sso.msp.gouv.qc.ca/apps/tilecache/tilecache.py?" orthophotos 8 15 "-1257720,-155000, 1333000, 2435720"

3 type of error:
