squid die (malloc error) on AIX 4.2.1

Dear Squid Admins,

        We are setup a squid (1.1.14) on powerpc-ibm-aix4.2.1, and we used
native AIX C compiler to make the execute program. Sometime the squid will
die for malloc error, but we have 327 Mbyte memory. After read the faq
(http://squid.nlanr.net/Squid/FAQ/FAQ.html), we know that we have addressed
the memory configure on OS level, can anyone kindly teach me that how to
tune up the parameters on AIX 4.2.1 ?

Here is the configure we currently defined :

Hardware :
        AIX 4.2.1
        21.6 G cache space
        memory - 327 M

Software :

For Squid config :
        Squid 1.1.14
        cache_mem 280 <-- just place safe
        cache_swap 21 G

For AIX OS config :
  Maximum number of PROCESSES allowed per user [240]
  Maximum number of pages in block I/O BUFFER CACHE [20]
  Maximum Kbytes of real memory allowed for MBUFS [0]
  HIGH water mark for pending write I/Os per file [0]
  LOW water mark for pending write I/Os per file [0]
  Amount of usable physical memory in Kbytes 327680

Thanks a lot,
