Have you verified that you have not filled up the disk or run out of inodes?
# check the diskspace with
df -h
# check for inode issues
touch /path/to/cache/test.junk
# if the touch failed then you have run out of inodes
# otherwise clean up
rm /path/to/cache/test.junk
Thanks,

I don't have a specific advice to give unfortunately. There have been
some fixes lately (macpcache only, not mod-geocache) to the way
multiple threads accessed the curl library that might help, so you
might want to try with a fresh checkout from the mapserver svn.

Thomas,
My command is below, I'm using a disk cache, my config file is below.

what seed command were you using, and what kind of cache ?

Thanks Thomas,
The complete error message is below. Do you have any idea what would
cause this error - why would mapcache fail to create or delete the
lockfile.

The log message should be more explicit, and contain the reason of the
unsuccessful removal. In any case, looking at the code, this error
will have interrupted the seeding process.

Hi All,
I hope this is the right spot to post MapCache questions. I had
seeded a large area and receive the error "failed to remove lockfile".
It appears that this error(s) happens at the end of the seeding but
it is hard tell as the process has been running for a few days. Does
this error kill the seeder process or is it simply a warning?
Regards
