Well, I just extracted 1.2.5 binary from
jakarta-tomcat-connectors-jk-1.2.5-solaris8-sparc-apache-1.3.28.tar.gz and replaced it
with my
existing mod_jk.so. (BTW, is there anyway to have mod_jk out its version number? I
didn't see
any version info in mod_jk.log even with "debug" log level". After stopping and
restarting httpd,
my test script shows that it's still chewing up fd's on httpd restart:
#!/bin/sh
i=0
while true
do
if [ -r /usr/local/bin/httpd/logs/httpd.pid ]; then
i=`expr $i + 1`
FILES=`/usr/local/bin/lsof | grep mod_jk.log | wc -l`
kill -USR1 `cat /usr/local/bin/logs/httpd.pid`
STATUS=$?
echo "`date`: i=$i; kill status=$STATUS; lsof mod_jk.log =$FILES"
if [ $STATUS -eq 0 ]; then
sleep 10
else
echo "kill failed"
exit 1
fi
else
echo "httpd not running"
fi
done
script output:
Tue Apr 6 16:23:18 PDT 2004: i=1; kill status=0; lsof mod_jk.log = 42
Tue Apr 6 16:23:30 PDT 2004: i=2; kill status=0; lsof mod_jk.log = 63
Tue Apr 6 16:23:42 PDT 2004: i=3; kill status=0; lsof mod_jk.log = 84
Tue Apr 6 16:23:55 PDT 2004: i=4; kill status=0; lsof mod_jk.log = 105
Tue Apr 6 16:24:07 PDT 2004: i=5; kill status=0; lsof mod_jk.log = 126
httpd instance count = 21 (1 parent + 20 children)
on init, mod_jk.log count = 42 => 2 * 21
subsequent graceful restart adds 21 more each time!
Eventually httpd crashed with too many open files!
