[Serusers] Need help: SER and MYSQL issue: PID file /var/run/ser.pid does not exist

Hi all, I need help to fix the following issue which only occurs when I am loading mysql.so. The problem is that serctl will fail to start SER and sometimes if SER start with service SER command. SER process is not found. I have observed that for all those issues, the cause is as system log as follows: Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: Maxfwd module- initializing Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: new_connection(): Client does not support authentication protocol requested by server; consider upgrading MySQL client Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: db_init(): Could not create a connection Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: ERROR: uridb_db_ver: unable to open database connection Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: ERROR: uri_db:mod_init(): Error while querying table version Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: init_mod(): Error while initializing module uri_db When those situation occur SER always unable to start, please see this message: Starting SER : PID file /var/run/ser.pid does not exist -- SER start failed I think it is to do with mysql connection. I will appreciate if someone, please help me how to fix this. I am sure a number of other people will be facing this issue as well. Please help !! Please Help! Thanks Dhiman
