Thanks Arthur, how do I change the number of non-convergent cases? Or should I just code
the bootstrap in hansel myself?

Subject: Re: [Gretl-users] Confidence bounds on IRF
@Sven: I think he speaks about the native irf() command.
I had a similar issue in the past. We discussed this a while ago. The problem may occur if
your data show excessive collinearity, for instance. If this happens more than 10 times
within the 999 bootstrap replications, gretl breaks the loop and gives this error
First, I circumenvented this issue by increasing the number of possible unstable cases in
the C-code, before I programmed it myself. Alternatively, one could increase the numbers
of non-convergent cases to, let's say, 99 or so.

Are you talking about the SVAR package here?
