UPDATE: I found a solution to this (but it's at the bottom because it was long after the bounty on this question ended). It's the one with the checkmark. If it works for you, please leave a comment.
I'm having a problem where my computer (Macbook Pro, 8GB RAM, OS 10.8) will not to attempt to load certain websites. Nothing fixes it except for rebooting. This occurs when nothing else is obviously wrong with my computer or internet connection, and when other sites load without problems.
When this occurs, here are the errors I get:
Error 13 (net::ERR_OUT_OF_MEMORY)
"The error is: 'The operation couldn't be completed. Cannot allocate memory.' (NSPOSIXErrorDomain:12)"
- Firefox: No response after entering the URL and pressing return (no error message, no throbber to indicate that it's loading or trying to contact the site).
PING google.com (188.8.131.52): 56 data bytes ping: sendto: Cannot allocate memory ping: sendto: Cannot allocate memory Request timeout for icmp_seq 0 ping: sendto: Cannot allocate memory Request timeout for icmp_seq 1
(after which I canceled out)
The first time I noticed this, it occurred for one or two sites I tried to visit. I was still able to use facebook and google. Later in the day, the error extended to facebook and google as well. After rebooting, those sites became accessible again, but later on I became unable to access other sites (stackexchange.com, surveygizmo.com).
Some other notes:
- I can confirm that this happens on multiple wireless networks and VPNs.
- At the moment this was happening I had 2 GB of RAM "inactive" and 500 MB "free" out of 8 GB total, so I'm not actually out of memory. Other websites and applications are responding snappily and there's no sign of excessive swapping.
- The response from ping seems to suggest that the problem doesn't affect DNS (though the IP address could have been cached somewhere).
I've only found one other reference to this problem, in this Apple support thread. No solution was found except for rebooting.
NOTE: This is not a problem with running out of RAM
Activity Monitor shows plenty of free / inactive memory. There's not an excessive amount of paging going on. Other websites load without problems. There may be some other kind of memory allocation error going on, but I can't imagine any way that a plain old RAM shortage would disable certain specific websites, with no other impact on performance.
