Hi there,

I've written a Perl code to get Foursquare data through its API. The code works fine for about a day or two. Then it starts throwing the following error:

error while setting up ssl connection (SSL connect attempt failed error:1409C041:SSL routines:ssl3_setup_read_buffer:malloc failure)

Versions:
Perl: 5.22.1 (Strawberry Perl) Win32 version on 64 bit Win7

Any idea what might cause the error?
