DO NOT REPLY [Bug 46632] New: mod_jk's sockets close prematurely
when the server forks a child
https://issues.apache.org/bugzilla/show_bug.cgi?id=46632
Summary: mod_jk's sockets close prematurely when the server forks
a child
Product: Tomcat Connectors
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_jk
AssignedTo: dev@tomcat.apache.org
ReportedBy: jleslie@placebase.com
mod_jk registers its cleanup handler to be called both during plain_cleanup and
child_cleanup:
apr_pool_cleanup_register(p, s, jk_apr_pool_cleanup, jk_apr_pool_cleanup);
So, whenever a server forks a child, ie, when mod_cgi creates its child
process, jk_apr_pool_cleanup() gets called. jk_apr_pool_cleanup() does a
shutdown() on its sockets, which closes down the socket for the parent process.
Maybe it should use close() instead of shutdown(), or be registered as
apr_pool_cleanup_register(p, s, jk_apr_pool_cleanup, jk_apr_pool_cleanup_null);
?
Note, with mod_jk 1.2.18, a load balancing worker isn't able to recover from
this, and it brings down the whole LB worker for awhile. 1.2.27 seems to be
able to recover.
After a CGI is hit and jk's sockets get closed underneath it, the logs look
like:
[Wed Jan 28 21:39:50 2009] [22841:42432] [info]
ajp_send_request::jk_ajp_common.c (1178): Socket 75 is not connected any more

Fixed in the SVN.
If needed the child cleanup certainly cannot be the same as standard pool
cleanup we are using currently.
