IIS sometimes "forgets" some http queries

-

hi,

i have following issue win 2003 r2 entreprise sp2 server 2gb ram.

it configured "gateway" between 2 infrastructures: java-based environment, , as400 db2 database. using "windev" code, gets http (soap) queries, transforms them in db2 sql queries, gets sql result , returns java client. it application running on server.  (don't ask me why such architecture).

so, same server launches queries, , built identically. such query takes 1 second fulfil, , there 10 queries each minute. however, encounter following issue:

sometimes (i.e. 2% of queries), java client sends http query not answer, , falls in timeout. used wireshark examining tcp/ip exchanged http data, see each query entering server , being acknowledged not being answered. "missing answers" fall in timeout, see tcp/ip query in wireshark, see no trace of http query in iis log file. also, windev component runs on iis not execute, and, of course, nothing sent client.

why see http tcp/ip entering server, not being processed iis (or @ least not being logged in iis log file) ? how may further diagnose , avoid "forgetting" these queries ?

yours, a.m.
