[Tilecache] Random Seeding Errors

[Frank Porcelli]

Hi Group -

 

We're running tilecache 2.01 on a Linux OS (using mod_python and Apache 2.2)
and have run into an issue where we receive random errors while running the
tilecache_seed.py command. It seems that the script will run for a while but
then all of the sudden return an exception and end abruptly. Below is the
exception output. Does anyone have any idea what could be causing this?

 

11 (000737, 001401) = (-115.2246 33.1348 -115.1367 33.2227) [0.0002s :
