From what you say here, there's no reason to believe that your problem
has been mentioned at all.

Signal 10 is SIGBUS (bus error), an error detected by the hardware.
The most frequent causes are bugs in the hardware and bugs in the
software.  The only way to find out what causes the problem is to
investigate further.  Never make the assumption that any two SIGBUS
problems are related.  Still, SIGBUS is interesting, because just
about every such error in FreeBSD is reported as a SIGSEGV (signal
11).

I can't confirm that at all.  I've been chasing a number of very
specific problems for some time, and as far as I can tell, there are

Re: MySQL Signal 10 on FreeBSD 6.0-RELEASE-P6

Thanks for the reply. I apologize, I should have been more clear with my 
first paragraph in my email. I have found several other somewhat similar 
problems with MySQL on FreeBSD 6.0 but with the MySQL 4.1.x series.

Nothing in the Bug report you suggested bears much resemblance at first 
glance. I originally thought this was a too many connections for the 
server (physical server) problem, so I dropped the max connections to 20 
and still got a signal 10. I also played with other numbers as the max 
connections but no matter what about once an hour a SIGBUS error would 
appear.

I have enabled --log and --core-file on my mysql server and I am trying 
to determine if a specific query is causing the problem, however I 
highly doubt this. Hopefully when it crashes the core file will be able 
to shed some light on the problem at hand.

Just as I was typing I had tail running on the log file and error log 
files and I caught a signal 10, at the time there was no query that 
stood out that hadn't been queried previously. If you like I could send 
the queries that preceded the signal 10, but I doubt they will do any 
good. There are 4 queries and about 25 quits, in the minute leading up 
to the crash.

I do have a core dump file and I am attempting to gather information, 
however my knowledge on inspecting core dumps is limited, I am willing 
to host the file somewhere if you care to look at it to help determine 
the cause.

Many thanks.

Re: Gotta start somewhere ... how many of us are really out there?

My calculations are off, I though the monthly periodic was relative to
the system install date. Here are the new numbers:

Lets say each client sends 20 bytes and their are 10^7 clients for a
total of 190.7MB per month. Now... Lets say 50% (10^6.7) of those
clients are set to UTC and all of them trigger on the first of the
month within 5 minutes of each other (10^6 per minute). This equates
to 16706 clients per second. We would need 326KB/s or 2610Kbit/s to
handle this load. This is a problem, even half of that is a problem.

openssl and apache

hi there,

uname -a:

FreeBSD cirrus.dfi.net.au 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Sun Jul  9 
12:08:32 EST 2006 amac <at> cirrus.dfi.net.au:/usr/src/sys/i386/compile/NEWKERNEL  i3861~

i recently got ssl running with apache. i'm not quite sure how it 
happened, but at some point after this i could not longer ssh into the 
box. i went into the data centre and found that when i tried to ssh out of 
the machine, the error:

OpenSSL Version Mismatch

appeared on the screen. It was quite important to get this working, and 
some googling turned up the possibility that this was because there were 
two versions of openssl installed on the machine. i did:

cd /usr/ports/security/openssl
make deinstall

and i could then ssh in and out of the box. however, now when i request a 
page using https from this machine the error:

[Tue Aug 01 13:55:22 2006] [error] [client 125.62.65.184] Invalid method 
in request \x80g\x01\x03

shows up in my apache logs. if i try:

openssl s_client -connect my.host:443

See a need, fill a need.  Since you can clearly see the person wasn't given
adequate information, then go ahead and give him the information.  Unless
people like you and me and the rest of us ordinary users take responsibility
for these responses, a lot of them will fall through the cracks since the
developers have limited time to answer them.

Nobody ever complained about being given too much information.

I'm running SpamAssassin and spamass-milter. They seem to do an okay job.

switching from linux to freebsd

Hello. I'm interested in moving my server from linux to freeBSD, but
have several questions:
1. What is the freebsd equivalent of lvm? I'd like to resize volumes,
add/delete volumes, etc. Currently I have my linux root on LVM with ext3
as a filesystem, which I can grow/shrink when I want, if one part runs
out of space. Will a shrinkfs command be added to freebsd like growfs is
already?
2. Can Ufs handle crashes very well, or is a very long fsck needed like
the old ext2 days?

3. is the restriction of NFS-servers only mounting on partition
boundaries going to be removed in the future, if it even still exists?

Thanks,
Tyler

Safe card to replace for ICP Vortex GDT8514RZ ...


I have a remote server, running the above RAID controller, that, as most 
ppl here have seen over the past few weeks, is causing endless headaches 
...

Official word from Adaptec is that FreeBSD is no longer a supported 
platform, so, I either live with the deadlocks, or try and figure out a 
suitable replacement for the card ...

So, can anyone recommend a card to replace this with?  Its a remote 
server, so I'm looking for something that will be plug-n-play, same slot 
that the GDT is in ... I realize that I'll have to reformat the server 
afterwards ...
