2 problems :
- PXE booting which does no longer work (I'm myself
investigating the case, as the rc* files for 4.2-Release are broken)
- Signal 11 when building world : this is **usually** the mark of
marginal hardware, which runs ok when no loads are applied
on the system, but fails when a big computation like "make world"
runs. The solution can be : use a better power supply (perhaps
also a stronger one), check your RAM, do not overclock your CPU,
check the fan on the CPU, ...

Subject: compiler and network problems since update
Dear Sirs.
Maybe it is only a kind of subjective impression or some kind of bad
luck, but since last week, after a cvsupdate and buldworld, I have
problems with TFTP and diskless clients. The phenomenon is that PXE
booting X stations run into a TFTP timeout when trying to boot.
I didn't change the configuration, but compiled new kernels and
installed the binaries proper on all systems (on the bootserver also).
I recompiled the DHCP server and installed it, too.
Another problem concerns to buildworld. Sometimes we have on our
server a buildworld running an some other climate research programs.
I realized that when these programs are running (compiled with Lahey
Fortran 95 for Linux) FreeBSD's gcc stops compiling with an error
SIG 11. This occurs many times. One time I realized a reset of the
server.
What are the causes of this failure? Hardware? A memory leak? A
bug in FreeBSD? Is there a kind of strategy to come closer to this problem?
I'm not very firm in debugging, so I have to ask for that.
Thanks,
Oliver
