Sorry, I'm recompiling right now. Dedicated servers crash with this error because of an engine limitation that doesn't occur with local listen servers.
This is caused by having too many entities (there is a stupid 4096 entity dictionary limit). The command line option -num_edicts 8192 _may_ solve the problem, but I'll just reduce the number of entities, recompile, and upload another version. I'm very sorry for the inconvenience - if only the dedicated server behaved identically to the listen server, this would've been caught much earlier (read: it's Valve's fault. And mine, for not testing on a dedicated server)
I have deleted a few hundred entities (mostly light_glow, props, and detail brushes).
I've installed the TF2 dedicated server and will test the map thoroughly. I will spawn some bots and have them flip out, but wether the map will accomodate 32 players in a real game, I cannot say after trying it on a live server.
