Hi Daniel,

This is most probably a JavaScript issue. Try disabling JavaScript,
PrefBar add-on, and checking whether you get the out-of-memory messages
if it is the case I am not sure what you or OpenBSD can do about it as
it is a program served by the site. Try blocking or not downloading the
asm.js but I'd venture a guess it will be of no use to you then then.

Web NO-point-Oh what can I say ;)

Good luck!

Sites in firefox stop loading with "out of memory" in console

2017-04-18 Thread Daniel Bolgheroni 
Ultimately some sites opened with Firefox 52 stop loading with "out of
memory" in console.  Two ofenders are https://app.wire.com and
https://www.protonmail.com/login, and both seem related to asm.js.

Note that Firefox doesn't crash, but the sites beeing loaded just stop
being loaded, and the F12 console notifies the error (console messages
below). This occurred also with the previous 51 version but not with
firefox-esr 45. Chrome works OK.

I already tweaked /etc/login.conf and the relevant part is:

staff:\
:datasize-cur=4096M:\
:datasize-max=infinity:\
:stacksize-cur=32M:\
:maxproc-max=512:\
:maxproc-cur=256:\
:ignorenologin:\
:requirehome@:\
:tc=default:

I tried to ktrace the process opening the ProtonMail login site. Two
"out of memory" messages in console corresponding to two "mmap -1 errno
12 Cannot allocate memory".

$ kdump -f ktrace.out | fgrep -C25 memory
