My system has more than 1 GB of RAM, and Im getting panics with kmem_map too small messages. What is wrong?
Normally, FreeBSD determines a number of kernel parameters, such as as the maximum number of files that can be open concurrently, from the amount of memory installed in the system. On systems with one gigabyte of RAM or more, this auto sizing mechanism may choose values that are too high: while starting up, the kernel allocates various tables and other structures that fill up most of the available kernel memory. Later on, while the system is running, the kernel has no more space left for dynamic memory allocations, and panics. Compile your own kernel, and add the VM_KMEM_SIZE_MAX to your kernel configuration file, increasing the maximum size to 400 MB (options VM_KMEM_SIZE_MAX=419430400). 400 MB appears to be sufficient for machines with up to 6 GB of memory.
