[Freeswitch-users] Apparent performance bottleneck and FS freeze

Tue Jul 23 00:42:25 MSD 2013

do you have manage-shared-appearance off too cos that re-enables presence?

edit sofia_glue.c on line 6614 and add a print to see what the sql is that
is being executed.

switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "SQL: [%s]\n", sql);

then make mod_sofia-install

and relaunch and try to catch a sample of what it's doing.
