[Serusers] ERROR message : MySQL server has gone away

[Leo Papadopoulos]

Kostas,

Kali Mera!!!

I am running FC5. I actually have configured SER to automatically start in
my init.d (let me know if you want to know how to do this) directory. After
the server boots up, I restart SER. Then it all works. I know this is not a
solution, but it can get you working. I think the key is to restart SER
AFTER the MySQL service starts.

Subject: Re: [Serusers] ERROR message : MySQL server has gone away

Greetings to the list.

We have a setup with ser-0.9.6 and mysql-5.0.19.
We have compiled everything from sources and we used mysql-5.0.19 sources
from
MySQL. Our x86 servers run Debian Sarge.

We have installed everything under /opt and we linked ser with the
mysql client libs under /opt/mysql/lib. There is no other installation
of MySQL (clients or development files).

In ser.cfg, we have the following mysql URIs:

fifo_db_url="mysql://ser:XXXXX@<IP_of_MySQL>/ser"
modparam("usrloc", "db_url", "mysql://ser:XXXXX@<IP_of_MySQL>/ser")


The PROBLEM:
We start ser via serctl (LD_LIBRARY_PATH needed) and we restart mysql.
If a new REGISTER comes to SER and then SER tries to write to MySQL,
we get the following error mesgs :
Apr 13 14:30:23 ./ser[26040]: submit_query(): MySQL server has gone away
Apr 13 14:30:23 ./ser[26040]: db_insert: Error while submitting query
Apr 13 14:30:23 ./ser[26040]: db_insert_ucontact(): Error while inserting
contact
Apr 13 14:30:23 ./ser[26040]: insert_ucontact(): Error while inserting in
database


Seems like SER's MySQL module does not auto-reconnect to MySQL server.


Please let us know what you need to further trace the issue.

thanks in advance for your help,
