Hi,
With WER, I can use with dumpType = 0, and CustomDumpFlags = 0, to generate small crash dump file enough to trace (1~2MB).
When use procdump -e -mc 0, it doesn't work, it generates ~30MB crash dump size, then I test with procdump -e -mc 2 (for full memory), it still ~30MB.
Is there something I missed at here?
Thanks

All threads of the process are paused during the creation of the dump.
So it really depends on the type of dump how long the application beeing traced freezes.
