This means that your ``file'' table is 360 elements in size,
and that is almost full.

There are a number of ways:
1. The quick way
The `maxusers' kernel parameter controls the static sizing of a number
of internal system tables by a complicated formula defined in
/sys/conf/param.c.
MAXFILES=2*NPROC, this means: each process opens approximately 2 files;
NPROC=20+16*MAXUSERS, this means: there is a 20 system processes, and
16 processes for each user.
In your case, the maxusers=10, thus, NPROC=180 and MAXFILES=360.
So, just increase your ``maxusers'' parameter and recompile the kernel.
2. Tuning
After ``config YOUR_KERNEL'', change to /sys/compile/YOUR_KERNEL
and edit the formulas in param.c (it is copied to this directory from
/sys/conf) for your taste.
For example:
#define NPROC (50 + 30 * MAXUSERS)
#define MAXFILES (NPROC*10)
