Hi Kern.
Maybe I was misunderstood. I'm not asking for support with running
bacula. I have a working, healthy system. Rather, I was asking if you
guys were interested in debugging a seg faulting process.
No, I didn't read the kaboom section, so I didn't know that bacula will
force itself to segfault. I generally jump to the conclusion that a
segfault in one version that doesn't happen in the previous, working
version, is a coding error, and want to help in debugging/fixing that. A
crash caused solely by an upgrade performed according to the
documentation is probably not really a "support issue", is it?
I guess if you guys don't want help finding and fixing bugs.. I can
respect that.
It will probably take me a couple of weeks to fix or at least fully
identify this problem by myself. Would it be out of line to post patches
here, should I find that there is, in fact, a problem with the code?
