FS-4931 --resolve ok, the binary also tries to make the dir but its probably failing from dropped perms.  probably if the freeswitch user had write perms in /var/run it would also work

FS-4928 doing 100 calls I found 7 million calls to toupper, this patch replaces it with an inline optimized one I found online.  Not sure it helps but maybe you can profile it again with latest.

optimisations.
