When publishing a BrokerEvent that has more than 30 nested structures i.e MR_DTL > 30 the publishRequestAndWait() API crashes silently with no error/exceptions returned. Is there any kind of ‘hidden’ limit on how many nested items to include on a document/event ?

When sending event with header + MR_DTL <= 30 items - API works correctly and reply event(s) are also received as expected…

<<
eventtype Dist::CREWS::MaterialReservation::TransferMRRequest_01 {
unicode_string HDR_ITEM1;
unicode_string HDR_ITEM2;
struct {
unicode_string DETAIL_FIELD1;
unicode_string DETAIL_FIELD2;
unicode_string DETAIL_FIELD3;
} MR_DTL;
}

<< /* Application source snippet */
try {
events = c.publishRequestAndWait(e, 120000);
} catch (BrokerException ex) {
s = "80 " + “(#” + curHdrSeqNo + ") - Error on publish - " + ex;
writeLog(s);
exit(c);
return;
}

NOTE: We’re running this Application within Oracle 8.1.7 JVM (JDK 1.2+) with plenty of memory setup to handle sending these sized events.
java_pool_size = 125 MB
shared_pool_size = 150 MB

We have also tried publish(), deliver() APIs with same results.

Would appreciate any feedback.
