Hi,

Nope, I'm still on Debian 5.0... in transit to CentOS 5.3 but it needs to wait a bit.
i was talking about gdb, not gcc and was trying to recompile FS with debug symbols on: CFLAGS="-g -ggdb" MOD_CFLAGS="-g -ggdb".

yes, I understand that gcc segfault most probably means only one thing... HW isues. This is sometihng that I'm going to check tomorrow.... running memtest to see what i get. Also, I will repeat the same test with a new block of RAM.


Maybe i didn't explain myself well... apologize.

T.

One of the things that -hp does is call "memlockall" which disables swapping which uses more memory which makes hitting a land mine in your ram chip much more likely.

On the other hand:

Since you are talking about "with" and "without" gcc support I am going to guess you are on Solaris which you probably should have mentioned before.
it's possible that some of the more aggressive things activated by -hp is not possible on that platform.  If so we either have to identify that and disable it or disable hp completely for Solaris.

Either way, gcc randomly crashing is never ok and is a symptom of a pretty serious issue.

Are you using 2 separate fresh checkouts for both suncc and gcc builds because it's not possible to switch the same source tree once it's already configured for one of them.

Hi Anthony,

it is not the machine ... and yep there was some memory related issue ... but this was caused by my module ....

So, to summarize.. i had two issues:

  1. FS crashing without any notice (at 5 CPS)
  2. Unable to recompile FS with gdb support


The first issue was actually related to "-hp" switch i was using in my startup script. With it, FS was crashing without any notice (even on low traffic) and regardless if i load my custom modules or not.
The second issue was related to many FS crashes having my module loaded... I found it later and fixed that.


So, after the machine cleanup I rebuild FS with gdb support without any issues.
Of course i sow this log .. but i didn't realize for a while... and after that i was fighting with crashes caused by "-hp" ... also, it was quite late as well ended up at 3 AM :P



Anyhow, the poit is; FS works well with my custom module. It just finished 2 mil. calls (with media) at 100 CPS having ~1600 simultaneous calls... well, thats something :P.

This is a FATAL error to have on your machine.
It's failing during the build.  This is your compiler crashing while trying to build the software.
This is very bad.
You most likely have a hardware failure and need to replace the machine or at the very least all of the memory chips.

hi Brian,

well, there is no coredump at all... and when i start FS with gdb it doesn't crash :P
I need to do some more testing and will come back to you.

This looks like gcc is segfaulting can you provide me a complete backtrace of the core file that dumps from FreeSWITCH? 


It sounds like you might have bad ram or bad hardware... gcc crashing is usually a sign something is really wrong with your machine.

Of course I'm using the latest trunk...

Can anyone help?
