I noticed that the JDK 1.3.1_05 release notes mention a known bug that could
potentially be the cause of our "out of control threads" problem. This bug basically
indicated that if a socket is closed while waiting on a read, the socket may not ever
timeout.
This *could* be what is causing the out of control processes you are seeing,
more can be found at:
http://developer.java.sun.com/developer/bugParade/bugs/4344135.html
The workaround that can be used is documented as follows:
On Linux platforms, a thread that is waiting on an I/O operation will not wake up if a
file involved in the I/O operation is closed. This problem is being tracked as bug
4344135. To avoid this problem, set the J2SE_PREEMPTCLOSE environment variable to 1.
J2SE_PREEMPTCLOSE=1
export J2SE_PREEMPTCLOSE
How can you test this workaround out?
Open /bin/coldfusion, find the section:
[note the below is line-wrapped]
Linux)
OS=Linux
CFSTART='su $RUNTIME_USER -s /bin/sh -c "export LD_ASSUME_KERNEL=2.2.9; export
PATH=$PATH:$CF_DIR/runtime/bin; export LD_LIBRARY_PATH=$LD_LIBRARY_PATH; nohup
$CF_DIR/bin/cfusion -autorestart -start default &"'
Change the above to:
Linux)
OS=Linux
CFSTART='su $RUNTIME_USER -s /bin/sh -c "export J2SE_PREEMPTCLOSE=1; export
LD_ASSUME_KERNEL=2.2.9; export PATH=$PATH:$CF_DIR/runtime/bin; export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH; nohup $CF_DIR/bin/cfusion -autorestart -start
default &"'
Save the file, and restart CFMX
Let me know if this helps.
