Has anyone else had any issues with .pbo's in the MPMissions folder? I'm able to connect and select, all that's fine (default missions run fine), however, if I use a custom .pbo (a few random maps from Armaholic, a few from the Steam Workshop) I tend to freeze randomly while in 'receiving data' from the server - I maybe reach 1/4th of the file before the freeze. Unsure which logs to check as I saw nothing unusual about maps in the net.log or the other log in the directory. Perhaps I'm not waiting long enough - I'm not sure.
For what it's worth I am on Ubuntu 12.10 64bit through a VPS with some low spec hardware but I was seeing 10-25 server FPS while playing around in the CO-10 default maps. Only planning to keep this server for squad operations (5-8 man), anyhow.
Just some information from the logs, an excerpt really, after in which I had to take the server down. Nothing of note in the net.log and no .rtp to be found (not on my home PC). I did some digging and found nothing similar to a3\map_altis\data\roads\roads.shp unless that's something within a3.pbo (which is in the addons folder). Don't know much about how Arma's file system works to give any good input myself. :
