I have been having trouble with this module (and other projects) using the included set of capability flags (0x3499c) on a specific host. I took some time to analyze the problem and it appears to be with the included flag set. In my case (and I suspect others'), the target node was rejecting the client with "not_allowed". After testing I found that simply adding DFLAG_BIG_CREATION (0x40000) allowed this exploit to work, both on the host I was having trouble with, and an older one where this (unmodified) exploit was working. Breakdown of flags is below.
```
0x0007499c == 0b0000 0000 0111 0100 1001 1001 1100

| |||-- DFLAG__UTF8_ATOMS
