sysctl can do this: |
| 14 |
|
| 15 |
carcharias # sysctl -a | grep sem |
| 16 |
kernel.sem = 250 32000 32 128 |
| 17 |
carcharias # sysctl -e kernel.sem="500 32000 64 256" |
| 18 |
kernel.sem = 500 32000 64 256 |
| 19 |
carcharias # sysctl -a | grep sem |
| 20 |
kernel.sem = 500 32000 64 256 |

I don't have any good document pointer as to what each of the values |
| 23 |
here mean, but googling should turn up something interesting. The |
| 24 |
32000 seems like a good sized real-world number, I suspect that is the |
| 25 |
system total, and the others might be per-user or per-process. So I |
| 26 |
would just start by doubling the others until you either cannot raise |
| 27 |
them any more or it works... |
