Hi,

Its defined in the Kernel Headers. The number of processes allowed for a
user is half the number allowed on the system. 4 process slots are reserved
for root. You can limit this with setrlimit(2). See "help ulimit" in bash.
#include <linux/tasks.h>:
---
#define NR_TASKS 512
#define MAX_TASKS_PER_USER (NR_TASKS/2)
#define MIN_TASKS_LEFT_FOR_ROOT 4
---
The Problem here is not the amount of process slots used, but the amount of
virtual memory... worst case u get "256*unshared" about 300k for a shell =
75M menory used by one user. This means if you add 50MB swap to your 40MB
ram the above test should not block you system anymore. Of course larger
process will use more memory. There is no overall limit for ram used by one
user...
You can use the lshell to enforce some limits:
lshell.conf:
default C60P30D20F24 // Default limits, 60 min's CPU time, 30 processes,
// 20Mb, 24 file descriptors
30*20MB=600MB swap needed to be safe...
Greetings
Bernd
