Error description
JSPs would not fully load on the browser, because of  lower
the linger timeout

customer had trouble with JSPs over a slow dialup
connection. WSAS 4.0.6 Adv on iSeries. JSPs would not fully load
on the browser. because of lwoer linger timeout
The eventual fix was to to be raised above the default of 20
seconds. The eventual fix was to raise the linger timeout from
20 to 100 using JVM system property
com.ibm.ws.linger to the websphere application server.
since it affects every WSAS version after 4.0.5. The hard-coded
value of 20 is not sufficient for connections over a slow
dialup.

The linger timeout cannot be overridden without a fix.
The fix provided for iseries WSAS does 2 things:
 1-showed the linger timeout being used
 2- allowed them to change it using the com.ibm.ws.linger
property
Local fix
no local fix
