commit 1092ec8b337595ed8d52accf41c6904d75b3689d: (limits), jid 0, uid 0: exited on signal 11 (core dumped)

It seems that after commit 1092ec8b337595ed8d52accf41c6904d75b3689d serveral
base services start to fail and dumping cores like

pid XXXX: (limits), jid 0, uid 0: exited on signal 11 (core dumped)

for instance sshd (base system), named (bind920, ports, just recompiled) and
many others.

I use a customized kernel, mostly commenting out unused driver and statically
compiling in ZFS/IPFW  ... just for the record.

Do I miss something (config option?)?

Kind regards,
