Apart from the change you suggested following are the changes I made to get moving ahead.

In file BundleEvent.h
bundlesendrequest:action_ int to int32_t
bundlereceivedevent:source_ int to u_int32_t
bundledeliveryevent:source_ int to u_int32_t

In file Forwardinginfo.h
Forwardinginfo:action_ int to int32_t
Forwardinginfo:state_ int to int32_t

In file Link.h
Link:state_ int to int32_t

In file Registration.h
Registration:failure_action_ int to int32_t

In file RouteEntry.h
RouteEntry:action_ int to int32_t

In RouteEntry.cc
at line 70,  p.addopt(new oasys::EnumOpt("action", fwdopts, &action_));
since action_ had been changed to int32_t from int, the required parameter
was int and it was getting int32_t. So I replaced the line with

int temp_action;
p.addopt(new oasys::EnumOpt("action", fwdopts, &temp_action));
action_=(int32_t)temp_action;

After these changes I had a linker error "undefined reference to xdr_free(int (*)(), char *)". xdr_free is called in two places: one in XDRUtils.h and the other in dtn_api.c. The call in dtn_api.c is present in the previous code that I used and it compiles well. The new call in XDRUtils.h is not present in the code I used earlier. This code compiles well on linux platforms but has the linker error with cygwin. One thing I noticed was that the call in dtn_api.c is from C code while that in XDRUtils.h is in C++ code. This is probably an issue of name mangling but am not sure how to get rid of it. Any suggestion in this regard would be useful.

Also please let me know if the type conversion that I have done are safe to use.

Thanks,

The links between the two nodes are configured as ONDEMAND links. Initially the link is up and node A has a large backlogged bundles to send to node B. While node A is still sending bundles to node B (the state of the link is "BUSY"), I manually bring down the link. In A's link table, the link from A to B stays in the "BUSY" state. Then I bring up the link again, the state of the link is still "BUSY". No bundle transmission takes place, however, despite that A has a large backlog. One or two minutes later, dtnd on A crashes. The last few lines of the log says [1161308836.034272 /dtn/cl/tcp/conn/192.168.2.12:5000/event_notifier debug] poll_with_notifier timed out [1161308836.034515 /dtn/cl/tcp/conn/192.168.2.12:5000/event_notifier debug] notifier wait timeout PANIC at conv_layers/TCPConvergenceLayer.cc:1767: bundle daemon took > 60 seconds to process event: fatal deadlock condition STACK TRACE: 0x80bdff3 0x80858c7 0x808916d 0x8089845 0x808a140 0x80e86d8 0x80e87b8 0xb7ddeced The line number is only for reference because I made some customization to the file TCPConvergenceLayer.cc. It actually points to these lines: if (total >= 60) { PANIC("bundle daemon took > 60 seconds to process event: " "fatal deadlock condition"); } It also seems that if I don't bring up the link again, the link will be stuck in the "BUSY" state but won't crash.
