are you sure? have you reinstalled/restarted openser? the logs are 
missing the "alloc'd from" details -- if you look in the wiki page there 
is an example of how logs should look like. is memlog set properly?

Now the mem log simply looks:
ul 17 17:37:36 ipshka openser[26651]:     6207. N  address=0x8378d0 
frag=0x8378c0 size=80 used=1
Jul 17 17:37:36 ipshka openser[26649]:     6390. N  address=0x837100 
frag=0x8370f0 size=128 used=1
Jul 17 17:37:36 ipshka openser[26652]:     6151. N  address=0x8356f0 
frag=0x8356e0 size=64 used=1
