Well your error message said that it was failing a malloc of about 75MB.
Without -bmaxdata, your total data segment size is 256MB (I think, plus
there are segments for code and stack), so it seems conceivable that you
could exhaust that much with expire. If you use -bmaxdata when building
expire, the compiler generates the code to handle a true data area
spanning multiple 256MB segments, trading-off a little speed for lots more
But do check the user limits and total paging space available too. Again,
I don't know what gcc or its library do on AIX/Power. If I get a chance
later today I'll have a look on our SP. My two news servers run on HPUX
rather than AIX.
