Hy there, 
I have a problem with running skipfish on a dedicated managed server, it fails 
after runnign 90 minutes with:
[-] PROGRAM ABORT : out of memory: can't allocate 81946 bytes
    Stop location : __DFL_ck_alloc(), alloc-inl.h:69

The commandline:
skipfish -W dictionaries/myown_keywords.wl -A myusername:mypassword -o 
../../skipfish-result-full/ http://myserver

The whole result is:

skipfish version 1.45b by <lcamtuf@google.com>

Please check the output of these commands:

ulimit -a
free

...to see if the amount of memory available to the program is not artificially 
limited.

Also, what's on the site? Is it heavy with images / videos, you may want to use 
-s to limit sample size.

Looks like the amount of per-process memory is capped at 64MB, and virtual / 
locked memory is capped at 256MB, by whoever configured this system. This is 
too low; please try this command:

ulimit -d unlimited -v unlimited -l unlimited

...and then run skipfish in the same session next.
