INN expire problems

[Heiner Lante]

Hello,

I have a problem during expire sometimes. When the expire starts INN stops 
working and some error messages can be found in the log files:

Syslog critical messages:
Sep 6 01:00:02 news innd: SERVER can't open history 
/usr/local/news/db/history: Cannot allocate memory
---------
Error log:
innd: dbz: getcore: mmap failed: Cannot allocate memory
innd: openhashtable: getcore failure: Cannot allocate memory
innd: can't dbzinit /usr/local/news/db/history Cannot allocate memory
innd: dbzclose: not opened!
innd: can't dbzclose /usr/local/news/db/history Cannot allocate memory
innd: SERVER can't open history /usr/local/news/db/history: Cannot allocate 
memory

Any idea what to do?

The server has 4 Gbyte of memory and has 4 Tbyte of disks.
