Hi
I have the following setup that causes intermittent problems:
- A number of file pollers that monitor a directory and send the names
of files found to a service component (direct routing)
- A service component that dispatches the received file names to a
processing module (via drools) and deletes the files as soon as it
receives and ack from processing
- A processing component that spawns threads (through a WorkManager) to
transfer files from A to B and sends an ack as soon as the transfer
completed.
All components are implemented as POJO objects and deployed in the
servicemix-lwcontainer.
If I sufficiently space the incoming files, then everything works fine.
However, if too many files arrive at the same time, then ServiceMix
freezes completely and does not recover anymore. From the first point I
infer that my setup should be correct and JBI compliant. However, how
can I determine whether the ESB is nearing saturation? How can I ensure
that I never bring the bus to its limits? I tried to read through the
JBI specs but could not find anything pertaining to the scaling of an
ESB implementation. Maybe some kind soul can point me to the right place?
Regards
Andreas
