Hello,

I have PIII 500 with 1GB of RAM on 4.9-RELEASE 
running Squid 2.5-STABLE4 and I got this error after a
few hours of Squid running.

proxy (squid): xmalloc: Unable to allocate 65535
bytes!

According to Squid FAQ

8.7 xmalloc: Unable to allocate 4096 bytes! 
by Henrik Nordstrom


Messages like "FATAL: xcalloc: Unable to allocate 4096
blocks of 1 bytes!" appear when Squid can't allocate
more memory, and on most operating systems (inclusive
BSD) there are only two possible reasons: 

1. The machine is out of swap 
2. The process' maximum data segment size has been
reached 

I got 2500MB swap file and isnt used when i try to use
the cmd top. How do i recompile a kernel with larger
datasize settings?

here's the options that i added im my kernel

maxusers        128
options         USER_LDT
options         DUMMYNET
options         IPFIREWALL
options         IPFIREWALL_VERBOSE
options         IPFIREWALL_VERBOSE_LIMIT=100
options         IPFIREWALL_FORWARD
options         IPFIREWALL_DEFAULT_TO_ACCEPT
options         IPDIVERT
options         HZ=80
options         NMBCLUSTERS=65536
