[SQU] connection lifetime expired

Hello all.

My clients are getting "Connection Lifetime Expired" messages even if my links to the Internet is not very loaded. My configuration is:

- 3 Internet links (1x256Kbps downstream only, 1x64Kbps duplex link, and 1x128Kbps duplex link)

- my clients belong to IP block 202.134.241.0/24 (IP block given with 128Kbps link)

- my proxy has:
    - 1 NIC (202.134.241.7/255.255.255.0 with alias 64.110.82.7/255.255.255.128)
    - 2x9Gb cheetah SCSI HD's (each one on a separate AIC7xxx controller) with 3Gb of the 1st disk mounted on /cache1 and 7Gb of the second disk mounted on /cache2
    - http_port is set to 202.134.241.7:3128 and tcp_outgoing_address is 64.110.82.7
    - IP forwarding is disabled

    - running 2.3.STABLE1 (will upgrade to 2.3.STABLE4 when RH7.0 comes)

- the default gateway of my proxy is the router to which the 64Kbps is connected to and which has been given a secondary IP of 64.110.82.126 (basically, my proxy uses the 64Kbps link for outbound traffic and uses the 256Kbps downstream-only link for inbound traffic)

What is causing this message to appear even if my links haven't even reached their CIR's? Also, df -h reports /cache1 as being only 16% used and /cache2 is only 14% used. My store.log files have repeating entries of SWAPOUT and RELEASED. I've tried commenting out client_lifetime as suggested in the archives but it didnt solve the problem. Any suggestions?

Thanks.

M. Yu
