[SOLVED]ISPCONFIG3 MULTISERVER NOT SYNC

I have ispconfig3 to multiserver config active from 4 years with this architecture:
- master server with active only dns (debian 6)
- web server with active ftp and web (debian 7)
- mail server with active mail and mailinglist (debian 6)
- db server with only server (debian 6)
the ispconfig version is 3.0.5.4p5 with ids active to all servers
From a few days when i create or modify any service from master the sync doesn't work, such as:
- if i delete a client with all service this is delete from master db but not any files an not delete to all other server
- if i modify any service this are correctly upgraded to master but not to other servers
- if i create a new client and relative services this are correctly created to master but not to other servers
- if i resync services from master this respond correctly but non sync with other server

Not any process are visibile from monitor->jobqueue and all crontab from servers are not modified all server connect correctly to master db.

What happened?

Tnk to all

 

All slave server work and conntect to muster but no process are stored to jobqueue for any operatrions from master so that any create or delete service are not effect to slave servers

 

To sys_datalog table of master server there are operations for slave server but that are not worked.
If operations are into sys_datalog tha will'be appear to jobqueue ?
If i resync any service from tool menu that oprerations are inserted to sys_datalog but not processed from slave server!!!

 

OHHH yes i have truncated sys_datalog from master so i must repeat the truncate table sys_datalog and update the "update" column of any server in the server table to 1
