--- Comment #5 from Rainer Jung <rainer.jung@kippdata.de> 2012-03-09 18:57:11 UTC ---
The problem seems to happen, when mod_jk reveiced the final package from the
AJP back end and at the end of the response request cycle calls
ap_finalize_request_protocol(). The connection to the client is an HTTPS
connection and maybe it happens during lingering close? Was the lsof taken
during the spining CPU? The lsof output does not contain the client connection,
so it seems that connection was already closed.

The loop seems to be in OpenSSL. What looks suspicious in the dumps is
len=0x7fff95282a50 in ssl_io_input_read().

I don't have a real recommendation here.

Rainer
