Question

I have a Java application running under JBoss AS 7 that is used to call a fairly complicated bash script using Runtime.getRuntime().exec(command). The bash script is failing because cvs is reporting that it is running out of memory (the error was “E342: Out of memory!” to be exact).

So should I be increasing the amount of memory available to JBoss AS (with JAVA_OPTS=”-Xms256m -Xmx2048m” or something similar), or does this indicate that the OS itself has run out of memory?

Answer 1

It turns out it was vim. I was running the script that called cvs under the empty command, which may have caused the issue. In the end I just created a script to edit the message file with a generic message:

#!/bin/sh
# Add a generic message
echo "Some Generic Message" > $1
# Update the time stamp. If you don't, you'll get a
# "Log message unchanged or not specified" error.
# the cvs timestamp comparison routine has a resolution
# of one second, so sleep to ensure that the timestamps
# are detected as being different.
sleep 1
touch $1
exit 0

Then set the EDITOR or CVSEDITOR environment variable to point to the script.
