I changed 'tcp_children' from 1 to 2. Restarted both OpenSIPSes. But still there's some difference: dialog:active_dialogs:: 67 dialog:active_dialogs:: 82 'opensipsctl fifo dlg_cluster_sync' hasn't equalized the number of active_dialogs. ----------------------------------------------- BR, Alexey http://alexeyka.zantsev.com/
