http://nagoya.apache.org/bugzilla/show_bug.cgi?id=26231 jk2_child_init called before make_child completes (in prefork MPM) Summary: jk2_child_init called before make_child completes (in prefork MPM) Product: Tomcat 5 Version: 5.0.16 Platform: PC OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: Native:JK AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I have built Apache 2.0.48 with the prefork MPM, and mod_jk2 using the tomcat 5.0.16 source tarball. When I start apache, I see some errors of the form: jk2_init() Can't find child 23459 in none of the 256 scoreboard slots I've traced this error to the jk2_child_init function in native2/server/mod_jk2.c. By adding additional logging calls to mod_jk2.c and the apache prefork.c file, I've verified that these messages are issued when jk2_child_init is called AFTER make_child (from prefork.c) is invoked, and BEFORE it completes. I think this is pretty good evidence of a race condition. I'm not familiar enough with the Apache codebase to figure out why this is happening, but I think it ought to be corrected nevertheless. (The only way I'm sure I could fix this is by putting a little delay and retry in jk2_child_init when the process can't be found in the apache scoreboard, but that seems tacky.) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
