Broken Pipe Errors
Hi
I have an install of Apache 1.3.26 talking over mod_jk (4.0.4) to Tomcat
4.0.4 on Solaris 8.
All seems to work fine for a while (a couple of days perhaps) - but after a
while I get a lot of broken pipe errors in catalina_out.xxx.txt. I
previously thought these were due to a missmatch between the number of
tomcat processors (maxProcessors) and the number of Apache clients, but this
doesn't seem to be the case. The errors are as below.
2002-09-23 00:19:30 Ajp13Processor[8009][3] process: invoke
java.io.IOException: Broken pipe
at java.net.SocketOutputStream.socketWrite(Native Method)
at java.net.SocketOutputStream.write(SocketOutputStream.java:91)
at org.apache.ajp.Ajp13.send(Ajp13.java:525)

at
org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:551)
at java.lang.Thread.run(Thread.java:479)
Eventually I get the error (lots of times):
2002-09-23 10:02:05 Ajp13Connector[8009] No processor available, rejecting
this connection
Which is fairly serious as nobody can see the site at this point.
At this point direct connections to Tomcat (via its HTTP connector on port
8080) don't get a response either.
If anyone has any experience/info regarding this I would love to hear it.
Thanks,
Anthony.

RE: Broken Pipe Errors
Posted by Mike Jackson <mj...@cdi-hq.com>.
In my experience those broken pipe errors seem to happen most often when
Internet Exploder decided that the page hasn't changed. So they may or
may not be a real symtom of your problem. But I only got those when I
was directly connecting to tomcat, not when I'm using apache as a front
end. Don't know if that'll help, but maybe it will.
