[Samba] samba 4.1.3 -- multiple bugs & 1, 297 coredumps -- coredump backtrace + full-backtrace included
Hello,
A few months ago the distribution I use (Debian Testing) moved from Samba 3
to Samba 4 - I started seeing a lot of problems. Since then there are two
bugs I find occurring on a regular basis:
1. Consistent dumping core on a regular basis (very rarely, if ever
occurred with Samba 3)
a. $ ls -ltr *core*smbd* |wc -l
b. 1297
c. $ du -ach *core*smbd*|tail -n 1
d. 3.2G total
e. The cores are when I went to Samba 4 starting on December 22nd 2013
to current.
2. When I make changes on the Linux filesystem-the contents are not
updated from the Window's perspective, even if I refresh the window.
a. Further, if I close out the share and re-access it, then I can see
the updated contents.
3. Perhaps some optimizations I have been using under 3 have bugs or
are no longer recommended?
a. Here is my Samba configuration:
i.
