Peer unreachable for 240 seconds

I have a simple J2EE server client application. Its deployed on

weblogic server. Whenever my client is receiving large chunk of data

from server i get error saying "Peer is unreachable for 240 seconds".

I tried configuring heartbeat timeout (IdlePeriodsUntilTimeout) to 10

seconds (default value was 4). And my understanding was even if i

receive error it would say "Peer is unreachable for 600 seconds" (as

in both cases heartbeat PeriodLength is 60). But i still keep getting

error that peer is unreachable for 240 seconds.
I tried to find information about server tuning for this issue. But I

could not find anything else.
Any help or hint would be appreciated.

    Some information on the 240 seconds can be found here:

    Could be your network is not able to carry large chunks of data. You can check the packet size by using the ping utility, for example,
    ping -c 3 -M do -s 1468
    PING ( 1468(1496) bytes of data.
    1476 bytes from icmp_seq=1 ttl=64 time=0.019 ms
    1476 bytes from icmp_seq=2 ttl=64 time=0.024 ms
    1476 bytes from icmp_seq=3 ttl=64 time=0.024 ms
    --- ping statistics ---
    3 packets transmitted, 3 received, 0% packet loss, time 2000ms
    rtt min/avg/max/mdev = 0.019/0.022/0.024/0.004 ms
    The 1468 is the packet size for which a test is performed. If a message is shown that must be fragmented you know the packaet size is too large.
