mysql refuses to work with outside network connections..

[Mikhail P.]

Dear AMD64 Users,

This post is probably my last resort to get mysql working on AMD64..

Ok, so we've got new AMD64 box today. The role of the box is to be dedicated 
MySQL server for one site (php/mysql driven).
FreeBSD-5.2.1 amd64 was installed on it, so basically it all started as clean 
install. First thing I did - upgraded system to "-p9" and cvsup'ed ports 
tree.

Next, I installed mysql port (database/mysql40-server) as usual (the only 
option passed to make - "WITH_XCHARSET=all"). So far so good - mysql build 
complete in few minutes, and I started mysql server 
(/usr/local/etc/rc.d/mysql-server.sh start); created database and then 
imported mysql data from file into mysql - cheers, mysql runs fine.

what next? I need to connect to created mysql database from another server, so 
basically mysql to be used from network rather from local socket.
That's where all problems pop-up - content server cannot connect to MySQL 
server. I went to check logs, and found a lot of the following 
in /var/log/messages:

Sep  3 16:51:20 amd mysqld[60076]: warning: can't get client address: Bad file 
descriptor

next I went to check mysql's log in /var/db/mysql, and here's what was there 
(a lot of entries - on every connect from network) -

mysqld got signal 11;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

------------------------
key_buffer_size=16777216
read_buffer_size=258048
max_used_connections=0
max_connections=100
threads_connected=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 
92783 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.


Number of processes running now: 0

--------------------------


So basically mysql wasn't usable from network.

after playing with my.cnf, trying various mysql versions (mysql41-server), 
playing with network and everything I could suspect, I did not find what is 
the problem..

To summarize - MySQL works from localhost via mysql.sock, but does not from 
network.

mysql client from content server shows:

[miha]@[beer]:~> mysql -h 192.168.200.3 -u vh1
ERROR 2013: Lost connection to MySQL server during query
[miha]@[beer]:~>

and these logs appear on mysql server.

I'm totally lost to this point - I've read mailing lists, and I see a lot of 
people run MySQL on AMD64..

Here's hardware details (if that makes any sence at all):

CPU: AMD Athlon(tm) 64 Processor 3400+
RAM: 1.5GB
Motherboard: ASUS KV8 SE deluxe
SCSI Controller: ahd0: <Adaptec 29320A Ultra320 SCSI adapter> port 
0xb000-0xb0ff,0xb400-0xb4ff mem
 0xf3d00000-0xf3d01fff irq 10 at device 12.0 on pci0
aic7901: Ultra320 Wide Channel A, SCSI Id=7, PCI 33 or 66Mhz, 512 SCBs

SCSI drive: SeaGate 15k RPM SCSI, 18GB


Because machine has 1.5GB of available RAM, I don't think that:
"It is possible that mysqld could use up to 92783 Kbytes of memory"
log entries hold any truth.


I have attached current my.cnf (which is basically taken 
from /usr/local/share/mysql/my-medium.cnf).

I would *greatly* appreciate any pointers on this issue - I have searched 
google, all mailing lists, but could not find anything similar to my 
problem..

kind regards,
M.
