Hello,
thanks for the details and patch. I will try to look at later today.
Cheers,
Daniel

Hi,
I've been hunting a memory error in publish handling the last couple of days.
The error is on our old but good 3.1.x presence server.
Using memory debug, I located the memory leak in modules/presence/hash.c, function insert_phtable, line 492 (in trunk):
p= (pres_entry_t*)shm_malloc(size);
As far I can see there are two errors when deleting publish htable entries
1. When calling delete_phtable pres.event->type is used instead of pres.event->evp->type
2. When creating publish hashtable, p->publ_count is not set. (defaults to 0)
In delete_phtable, the following code is present
p->publ_count--;
if(p->publ_count== 0)
p->publ_count is probably decremented to -1 (unless the user have two active dialogs)
I attach a patch, which I would carefully test in a test environment :-)
Regards,
Kristian Høgh
