After upgrading from 7.1 to 7.3r4, some of my users (all on Mac OS-X) complains about not beeing able to access to our SSL VPN gateway.
a ping to my SSL Gateway reports following error:
> ping: sendto: Cannot allocate memory
Safari shows this error when accessing to SSL VPN gateway:
The error is: 'The operation couldn't be completed. Cannot allocate memory.' (NSPOSIXErrorDomain:12)
This seems to be related to a routing table completly broken (see screenshot).
Do you see the same issue on your sites?
The only way to solve this issue was to clear the routing table (disable/enable TCP/IP on advanced preference on Wi-Fi/Ethernet interface).
