--- Comment #2 from jan.pfei...@centrum.cz ---
It happens several times a day or even several times a hour. But it happens in
random manner. No single particular request can do it.
There are no clues in logs. At least for me. I have one qutie busy image
serving servlet which produces tons of different client abort exceptions,
closeNowException, Stream is not writable etc.
I can only guess it is about concurent access to it. I have other logs
available, if you want to look.
After latest crash i have found this (only relevant log output before crash):
Caused by: java.io.IOException: Unexpected error [120,001] writing data to the
APR/native socket [975,220,944] with wrapper

Do you want me to run some specific test or post server config or other logs?
