[Serusers] SER does not start with MySQL

[Sebastian Kigelman]

Hi there!!!... Iam newy in SER mailing list, and I have a problem with my
SER installation that I saw that other members have before, but I can't find
a solution to the issue.

I have installed the SER (v0.8.14), all works fine until I add MySQL support
to get persistent users. after that, when I run "serctl start" I get this
error: 

----------------------------------------------------------------
Starting SER : cat: /var/run/ser.pid: No such file or directory
started pid()
----------------------------------------------------------------

I have made some test to troubleshot this issue, for exsaplme: remplacing
DIR=... with the full path to SER executable in "serctl"... and also I
increase the debug level in "ser.cfg" to 7, and I get this output:

I couldn't find what is wrong in my configuration...

BTW, I can add, remove and edit users in MySQL Database using "serctl"
subscribers commands (that means that my SER machine is talking with MySQL
server as in expected)
