Yes, but it is pretty large. I'm not an ffs expert, but after reading in the SMM, the only limit I see is in the number of inodes allocated when the filesystem is created. See man newfs for the info on how many inodes are created. As I understand it, by default there is an inode created for every 4k of disk space per filesystem. So it is possible to create too many directories and use up all the inodes. That means you could only create 250 files in a MB of space. But for a 1gb filesystem that works out to 250,000 fiels so it should be enough. As it says in the manpage that means the average file is expected to be 4k. If yours is smaller you need more inodes. To get more inodes, you need to recreate the filesystem with a lower value for -i. More inodes means a longer fsck time also, so that is why the default is low I guess.
