I have a strange problem which I don't know how to describe accurately, but here goes:
we have a tomcat server running and every time a lot of jsp pages running under are changed, it seems the process forks and starts an additional tomcat process. When this happens neither process seems able to handle requests anymore.
Additional info:
Tomcat runs as: (using ps -aux)
/usr/local/jdk1.4.1/bin/java -jar -Dcatalina.home=/usr/local/jakarta-tomcat4.1 bin/bootstrap.jar start
java version:
Java version "1.4.1-p3"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-p3-webedit_12_sep_2003_15_53)
Java HotSpot(TM) Client VM (build 1.4.1-p3-webedit_12_sep_2003_15_53, mixed mode)
OS : freebsd versie 4.8
In the logs I see something like: type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception org.apache.jasper.JasperException: Unable to compile class for JSP An error occurred at line: -1 in the jsp file: null Generated servlet error: [javac] Since fork is true, ignoring compiler setting. [javac] Compiling 1 source file [javac] Since fork is true, ignoring compiler setting.
After killing all processes and starting tomcat again, everything works fine.
I can reproduce it as follows:
(16:47:43)[EMAIL PROTECTED] /usr/local/jakarta-tomcat4.1/webapps/ROOT/teletop >touch *
(16:47:47)[EMAIL PROTECTED] /usr/local/jakarta-tomcat4.1/webapps/ROOT/teletop >ps -ax | grep cata
32392 ?? S 4:46.83 /usr/local/jdk1.4.1/bin/java -jar -Dcatalina.home=/usr/local/jakarta-tomcat4.1 bin/bootstrap.jar start
Still ok up to this point, but after giving it some more time:
(16:50:16)[EMAIL PROTECTED] /usr/local/jakarta-tomcat4.1/webapps/ROOT/teletop >ps -ax | grep cata
32392 ?? S 4:58.50 /usr/local/jdk1.4.1/bin/java -jar -Dcatalina.home=/usr/local/jakarta-tomcat4.1 bin/bootstrap.jar start
34112 ?? R 0:28.19 /usr/local/jdk1.4.1/bin/java -jar -Dcatalina.home=/usr/local/jakarta-tomcat4.1 bin/bootstrap.jar start
34114 p1 S+ 0:00.00 grep cata
tada 2 processes...
haven't got a clue, anyone?
