Hi, I'am running : - varnishd (varnish-2.0.4) - linux kernel 2.6.27.10-grsec-xxxx-grs-ipv4-64
and it appears that the grsec Kernel repeatedly and unexpectedly sends signal 11 to the varnishd child. .../...

Is there any way to fix this. Remocve the GRSEC kernel ? Upgrade the kernel ? Varnish ? or whatever ?
