[strongSwan-dev] strongswan 4.6.2: charon unstable/crashes when establishing a lot of connections

Hi,

To me this definitely looks like an out of memory situation.

There are many other memory limits than just the number of memory
modules in your system. You're running strongSwan as a 32-bit
application, so you should consider the size of your virtual address
space. Also have a look at any memory related ulimits you have set.
