[OpenSIPS-Users] Presence - subscription does not exists problem

[Chris Maciejewski]

Hi Bogdan,

Another short video (switch to HD 1080p for better quality):

as you can see the subscription is initially visible both in MI and DB.

It seems it disappears both from memory and DB right the very same 
moment when the next re-subscription arrives.

In my config file I have:

modparam("presence", "subs_htable_size", 14)

which should give hash table of 16384. Is it possible that is not enough 
for my user population of around 4000 ?

pcap and traces (almost identical to the ones from me first post) below:
