Pipe Call Failed

Hello list,

The last 3 days I notice a weird problem with the current , I 've
built.After some time of work the system seems to cannot allocate memory
although there is plenty of it free.For example now , I try to run a
simple script that ssh'es to a host (the same with firefox and other
programms):


marinosi_at_loki:~$ diogenis
/usr/home/marinosi/bin/diogenis: Pipe call failed: Cannot allocate
memory
marinosi_at_loki:~$ strace diogenis
execve(0xbfbfe31c, [0xbfbfe7f0], [/* 0 vars */]PIOCWSTOP: Input/output
error
/usr/home/marinosi/bin/diogenis: Pipe call failed:
Cannot allocate memory

marinosi_at_loki:~$ strace firefox
execve(0xbfbfe31c, [0xbfbfe7f0], [/* 0 vars */]PIOCWSTOP: Input/output
error
/usr/local/bin/firefox: Pipe call failed: Cannot
allocate memory

And of course my kernel messages flood, telling that the
kern.ipc.maxpipekva exceeded the limit:
kern.ipc.maxpipekva exceeded; see tuning(7)


marinosi_at_loki:~$ sysctl kern.ipc.maxpipekva
kern.ipc.maxpipekva: 16777216
This is the limit also,  to my -STABLE laptop that works fine.

Something new committed to the kernel?
Thank you..
