[rrd-developers] Re: Strange lockup issue

[Bertelson, Tom (CAP, CARD)]

I too had a lockup problem, under Solaris.  The problem appeared when the
end time was greater that the last datapoint in the file.  Do the problems
go away if you decrease the end time?

Here's my fix, along with another that fixes calling the rrd_* routines
multiple times within a C program.  Hope this helps.
