Re: setting shmseg?

=> I am writing an application which makes heavy use of threads and shared

=> `ipcs -T` tells me that this is currently set to
=>      shmseg:     128 (max shared memory segments per process)
=> Is this changeable in some way or is it hardcoded in the kernel
=> someplace (thus necessitating a kernel recompile :( ) ?
=> If it is changeable than how?

   It is a sysctl. Try:

sysctl -w kern.ipc.shmseg=4096

   Larger values are possible; I haven't checked for a hard limit. You can
add it to /etc/sysctl.conf to have it set at boot time.
