Hi,
we are using the XMPP gateway modules:
• PUA
• PUA_XMPP
• XMPP
The behavior is ok but since the modules are started, the memory usage
is getting increased and now also the swap memory area is used.
I send to you the following information:
1. Numer of records from PUA and xmpp_presentity tables, they are quite stable:
SQL> select count(*) from pua;
COUNT(*)
----------
10218
SQL> select count(*) from xmpp_presentity;
COUNT(*)
----------
754
2. list of PKG fragments with gdb :

Is it a memory leak in one of these modules?
Thanks in advance and kind regards,
