More puzzing nmbclusters

[Konrad Neuwirth <konrad%mailathome.or.at@localhost>]

So the kernel tells me again: 

| WARNING: mclpool limit reached; increase kern.mbuf.nmbclusters
| WARNING: mclpool limit reached; increase kern.mbuf.nmbclusters
| WARNING: mclpool limit reached; increase kern.mbuf.nmbclusters
| WARNING: mclpool limit reached; increase kern.mbuf.nmbclusters
| WARNING: mclpool limit reached; increase kern.mbuf.nmbclusters

I'd love to, but how? 

This is the kernel we have live: 

| pinie# gdb /netbsd
| GNU gdb (GDB) 7.3.1
[SNIP]
| Reading symbols from /netbsd...done.
| (gdb) print nmbclusters 
| $1 = 131072

And what does it tell me?

| pinie# sysctl kern.mbuf.nmbclusters
| kern.mbuf.nmbclusters = 16384

So maybe … 

| pinie# sysctl -w kern.mbuf.nmbclusters=32768
| sysctl: kern.mbuf.nmbclusters: Invalid argument

No. The only result that doesn't produce an Invalid argument is … 16384. 

What can I do? 

This is a NetBSD/i386 machine with 2GB physical RAM. 

Thank you,
 Konrad
