Hello Rodrigo!
OK, I'll update Mono in few days.
Is XSP2 project still supported? Are there any commits to it since 3.2.6?
About Yandex. I don't know :)
I'm not an yandex employee.
Yandex.ru is just a russian public mail service like gmail or yahoo.
With kind regards,
Max Karavaev

Hey Maxim,
You should try a more recent mono. 3.2.6 is quite old.
Just curious, are you trying to use mono at yandex?

Hello!
I've just created ASP.Net website and ran it on Apache&mono on Linux.
And I've got strange situation. After 50.000-100.000 requests
mod-mono-server process unexpectedly become busy with 100% or 200%
(exactly) CPU load.
After restarting mono process via mono-ctl panel cpu consumption returns
to 1-3%.
I've found some errors like
[Wed Sep 03 16:02:57 2014] [error] (32)Broken pipe: write_data failed
[Wed Sep 03 16:02:57 2014] [error] (32)Broken pipe: write_data failed
[Wed Sep 03 16:02:57 2014] [error] command failed: failed to get client
block (data)
in apache error_log, but it seems like there are no relations in time
between these errors and busy moment.
So, the questions:
1) are there any way to know what is happening in this situation? What
threads are running, etc... I'm not sure the reason is in mono itself, may
be the reason is in my application. Full profiling on production server is
not possible, I mean just a few statistics,
2) if the reason is in garbage collector: are there any ways to tune it?
Or to switch from sgen to old Boehm or so on?
Any help are highly appreciated!
