please increase the HTTP request processing timeout (default value is
15mins) by setting
asadmin set
server-config.network-config.protocols.protocol.http-listener-1.http.request-timeout-seconds=NNN
where NNN the max number of *seconds* one single request might be
processing by a thread.
As I told the default value is 15mins, which means NNN=900, so you can
set any higher value.
