Subject "Critical poller failure" when using tcnative
Date Sat, 08 Apr 2006 16:17:31 GMT
Hi,

I'm trying to set the new issues.apache.org box up with Tomcat 5.5.16 +
tomcat-native-1.1.2 + httpd 2.2.0.  When requests come in, I'm seeing
these errors for almost every request in the logs:

Apr 8, 2006 3:28:47 PM org.apache.tomcat.util.net.AprEndpoint$Poller run
SEVERE: Critical poller failure (restarting poller): [3] No such process

We experienced this before on the old issues.apache.org box, but Remy
said he fixed it (and it is fixed on that box):

http://issues.apache.org/jira/browse/INFRA-716?page=all

I've tested both with the patched Tomcat that was working on the old box,
and Tomcat 5.5.16. I've tried with tcnative compiled against APR 1.2.2,
r383698 (the one working on the old box) and SVN head (r392544).

I've also tried starting Tomcat and then restarting httpd to reestablish
the connector connections. No difference.

If it's relevant, the httpd config is at:

https://svn.apache.org/repos/asf/infrastructure/trunk/httpd-conf/brutus.apache.org/vhosts/


Any suggestions? I can upgrade or recompile Tomcat with extra debugging if that
helps. The relevant code is AprEndpoint#run():

                    } else if (rv < 0) {
                        int errn = -rv;
                        /* Any non timeup or interrupted error is critical */
                        if ((errn != Status.TIMEUP) && (errn != Status.EINTR)) {
                            if (errn >  Status.APR_OS_START_USERERR) {
                                errn -=  Status.APR_OS_START_USERERR;
                            }
                            log.error(sm.getString("endpoint.poll.fail", "" + errn, Error.strerror(errn)));
                            // Handle poll critical failure
                            synchronized (this) {
                                destroy();
                                init();
                            }
                            continue;
                        }
                    }


I've appended the full stdout from startup.


Thanks,
Jeff
