what is the parser state (getEventType()) just before last next()?

that should not happen but as it happens it is very important that
you can reproduce it so we can pinpoint the root cause of the problem.

did you make sure that only one thread at any time is accessing
parser instance. the easiest approach is to to use pool of parser
instances that are reused to handle requests (typically each request
gets its own parser instance and not shared with other thread).
