[syslog-ng] Solaris 10 UDP overflows, message drops

I found http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22286 and disabled
optimization with -O0 in CFLAGS/CPPFLAGS, still getting the same exact
error.

I found this which seems to address the problem:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21613.  Seems to only be an
issue when using -fPIC with GCC 3.4 (I'm using 3.4.6).  I have to use
-fPIC to use the TLS references (I think).  I'm not sure where to go
from here, I don't fully understand the workaround in bug 21613 listing
(at the bottom), I guess I could move to a newer version of GCC?  I'm
not sure how much I'll break doing that, but it's worth a shot I
suppose.

All,

Sure enough, as Bazsi had suggested, the stopping point appears to be
ivykis compilation on Solaris 10.  I have a full suite of gcc tools
(including automake, autoheader, autoconf, flex, gcc, etc.) installed on
this machine from Sunfreeware.com.  The configure proceeds without any
errors.  When I try to get it to compile, I get the following error:

make[7]: Entering directory
`/root/syslog_tools/syslog-ng-3.3.0alpha2+20110426/lib/ivykis/modules'

I'm not even sure how to begin troubleshooting this, Google and Bing
yield nothing obvious either.  Ivykis must be fairly new, there's not
much in their indexes concerning it at all for that matter.  Have you
guys seen this when compiling with that snapshot that Gergely prepared?
Any hints for me?

The configure (which works):

./configure --enable-pcre --disable-ipv6 --enable-dynamic-linking
--enable-sun-streams --disable-mongodb

The configure report:

  SQL support (module)        : no

The various vars I've had to set to get things working (had to add
/usr/ccs/bin to get ar in path, had to add -fPIC to fix a TLS error,
stuck on current error).

# echo $CFLAGS
-fPIC -O3 -m32
# echo $PATH # all the GNU tools are in /usr/local
/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/usr/ucb:/usr/ccs/bin 

Thanks for any help anyone can give (ongoing!).  I'm also waiting on a
4.0 PE eval download to get allowed.  Hopefully I can give some updated
performance numbers in light of that getting installed soon (with the
write() and time() fixes Bazsi alluded to earlier).

Gergely,

Got it, trying to compile now.  Was having issues with the
configure/compilation of ivykis with the alpha2 release.  Will update
everyone soon, was out end of last week unplanned.

Thank you!

r.gz

sha1sum: 5d2bb56c9168e0e3eb95ee4342bd0171f6c24c5b
md5sum: d52ab242544366e5c6454a00e89b3ce6

Snapshot was taken from the state as of the 26th of april (the last
change in the repository). Hopefully this'll be easier to compile than
3.3.0alpha2, a bunch of fixes went in that should help in this area.

(Apologies for not putting this on a .balabit.hu domain, that needs more
administration than I was prepared to do for this task)
