I ran into the same problem. Was running into the datasize-cur=512M
limit in the staff section of login.conf
I'm not saying this is the right thing to do, but I bumped it to 1024M
and haven't had a firefox seg-fault since. This is a system I use as
my desktop, so I'm not concerned with other "staff" causing problems.
I believe this corresponds with "ulimit -d", so I could probably have
put "ulimit -d 1048575" in my .profile
---
Ha!, funny thing when I was looking at this:
$ ulimit -d
1048576
$ ulimit -d 1024M
ksh: 1024M: bad number `1024M'
$ ulimit -d 1048575
$ ulimit -d
1048575
$ ulimit -d 1048576
ksh: ulimit: exceeds allowable limit
$ ulimit -d 1048575
$ ulimit -d 1048577
ksh: ulimit: exceeds allowable limit
$ ulimit -d 1048574
Looks like login.conf will set it to 1048576K but ulimit -d will only
go up to 1048575K, <shrug>, what's 1K among friends :)
In case anyone cares, I'm using slightly old -current snapshot:
$ sysctl kern.version
kern.version=OpenBSD 5.2-current (GENERIC.MP) #8: Fri Dec 21 01:35:40 MST 2012
