Readme at the link stated below said that db_mode is a valid parameter. http://kamailio.org/docs/modules/3.2.x/modules_k/presence.html#id2546358
This patch fixes subscription restoration after kamailio-3.2.4 restart in case when db_mode of presence module is 0 (MEMORY_ONLY).
vitalik@work:~/src$ diff modules_k/presence/hash.c modules_k/presence/hash.c 264c264 < if(dbmode == DB_FALLBACK || dbmode == DB_MEMORY_ONLY) { ---
if(dbmode == DB_FALLBACK) {
Now it saves subscriptions in memory and periodically(db_update_period parameter) dumps them to the active_watchers table. After restart kamailio fills subscription hash table from the active_watchers db table.
Upgrade is a good suggestion as presence module of 3.3.х branch differs much from the one in the previous release and I hope it doesn't have described problems.. I have to port a few custom modules to switch to the new branch.

db_mode is 0 (DB_MEMORY_ONLY) and according to comments in the presence.h kamailio holds subscription in memory and periodically updates to db, but retrieves from db only at startup. And it's true, I see that kamailio tries to update the active_watchers table, but it never inserts new subscriptions there.
i suggest you upgrade to 3.3. according to its readme, subs_db_mode=0 means that db is disabled. perhaps it was the same with 3.2, which according to its readme does not have db_mode param.
