[SR-Users] presence bug

I would like to report a bug on the presence module kamailio 4.0.5 setting custom table names via modparam("presence", "presentity_table", "kam_presentity") modparam("presence", "active_watchers_table", "kam_active_watchers") modparam("presence", "watchers_table", "kam_watchers") does work, i can see entries on the table when logged in. however these things show up from time to time, seems like it is not looking for the custom table name. /usr/local/sbin/kamailio[20406]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Table 'kam.presentity' doesn't exist /usr/local/sbin/kamailio[20406]: ERROR: <core> [db_query.c:132]: db_do_query_internal(): error while submitting query /usr/local/sbin/kamailio[20406]: ERROR: <core> [db_query.c:429]: db_fetch_query_internal(): unable to query db for fetch /usr/local/sbin/kamailio[20406]: ERROR: presence [publish.c:108]: msg_presentity_clean(): failed to query database for expired messages /usr/local/sbin/kamailio[20406]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Table 'kam.presentity' doesn't exist /usr/local/sbin/kamailio[20406]: ERROR: <core> [db_query.c:291]: db_do_delete(): error while submitting query /usr/local/sbin/kamailio[20406]: ERROR: presence [publish.c:227]: msg_presentity_clean(): failed to delete expired records from DB /usr/local/sbin/kamailio[20406]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Table 'kam.watchers' doesn't exist /usr/local/sbin/kamailio[20406]: ERROR: <core> [db_query.c:291]: db_do_delete(): error while submitting query /usr/local/sbin/kamailio[20406]: ERROR: presence [subscribe.c:745]: msg_watchers_clean(): cleaning pending subscriptions /usr/local/sbin/kamailio[20406]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Table 'kam.active_watchers' doesn't exist /usr/local/sbin/kamailio[20406]: ERROR: <core> [db_query.c:291]: db_do_delete(): error while submitting query /usr/local/sbin/kamailio[20406]: ERROR: presence [subscribe.c:2220]: update_db_subs_timer(): deleting expired information from database Kelvin Chua
