[Serusers] Location table memory usage

Hi all, i am testing huge loads on location table in version 0.8.14 and see that: After increment PGK_MALLOC i can support 20.000 entries in the memory location table. This 20.000 entries are using around 12Mb of RAM memory on my linux RedHat 8.0. When this 20.000 contacts expires the table is cleaned but SER remain taking 12Mb of RAM. It is a normal operation or SER must perform some function to release the memory used by the location table when the contacts expire ?? #----------------------------------------------# version: 0.8.14 (i386/linux) flags: STATS:Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 @(#) $Id: main.c,v 1.168.4.3 2004/06/28 15:41:21 andrei Exp $ main.c compiled on 12:45:14 Jul 30 2004 with gcc 3.2 #----------------------------------------------# 140 processes: 138 sleeping, 2 running, 0 zombie, 0 stopped CPU states: 0.2% user, 0.7% system, 0.0% nice, 98.9% idle Mem: 513972K av, 162580K used, 351392K free, 0K shrd, 45532K buff Swap: 2096472K av, 0K used, 2096472K free 76892K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 486 mysql 15 0 16856 16M 2604 S 0.0 3.2 0:16 mysqld 25492 root 24 0 12904 12M 12764 S 0.0 2.5 0:02 ser #----------------------------------------------# Thanks Ezequiel Colombo
