I have had some rather odd issues with the SRX boxes but JTAC were pretty good at turning around fixes for me for my specific issues.

Since then I have had quite a lot of SRX boxes across the range running various MPLS services including MPLS over GRE with fragmentation/reassembly which has been working very well. Since 11.1R3 I've had no issues at all with them.

So yeah the new flow mode stuff had its issues, but as a *small* MPLS box it is very functional. Of course in MPLS mode, you turn the flow stuff off..
