RE: [ebxmlms-general] "Missing start boundary" exception when processing lot of message

[Morin F. <fm...@ax...>]

I updated javamail to the last version (1.3.2) but I always had the same
problem...
I'll try your suggestion to see what happen.

Thanks.

Objet : RE: [ebxmlms-general] "Missing start boundary" exception when
processing lot of message


I've seen this in three circumstances (not in hermes, but with jaxm)
- once in a system under load where there was a threadsafety issue and
one
receiver started reading data after the headers were already read.
- once where there was a wrong mail.jar which produced wrong headers,
but
that happened all the time, not specifically under load
- an text/xml response was produced, but not multipart mime as expected.

Otherwise I have no idea where it could come from. Can you turn on some
low
level debugging on http level?
