Yes all the VINA apps have some retry logic built into them. There are some circumstances such as shutting down windows which can cause the VINA sub process to error out in an unexpected way. If this occurs the app will temporarily exit and retry after a delay.

I had a surprise single SNS WU turn up a few days ago - unfortunately I didn't manage to capture the error log and the whole lot has now been wiped off the main log - suffice to say that it was sent out to about a dozen crunchers and every one was an Error reported WU - although credits were awarded, so I don't know if this was a known Error prone WU tried for consistency or if it was indeed a rogue one!! Either way, we can do without too many others of that species!!!
