I don't understand.
Would you like to explain me what "running with a profiler" mean, please?
I start agent running a start-agents.sh script, and zookeeper too.
/opt/manifoldcf/multiprocess-zk-example-proprietary/runzookeeper.sh
/opt/manifoldcf/multiprocess-zk-example-proprietary/start-agents.sh
Where start-agents.sh is:
#!/bin/bash -e
cd /opt/manifoldcf/multiprocess-zk-example-proprietary/
if [ -e "$JAVA_HOME"/bin/java ] ; then
if [ -f ./properties.xml ] ; then
./executecommand.sh -Dorg.apache.manifoldcf.processid=A
org.apache.manifoldcf.agents.AgentRun
exit $?
else
echo "Working directory contains no properties.xml file." 1>&2
exit 1
fi
else
echo "Environment variable JAVA_HOME is not properly set." 1>&2
exit 1
fi
Thanks a lot Karl.

It looks like you are running with a profiler? That uses a lot of memory.

Is it an Agent configuration?

When you get a hang like this, getting a thread dump of the agents process is
essential to figure out what the issue is. You can't assume that a transient
error would block anything because that's not how ManifoldCF works, at all.
Errors push the document in question back onto the queue with a retry time.

Hi Karl.
But I noted that the job was hanging, the document processed was stucked on the
same number, no further document processing from the 6 a.m until I restart Agent

Hi, "Possibly transient issue" means that the error will be retried anyway,
according to a schedule. There should not need to be any requirement to shut
down the agents process and restart.

So, I have to stop the agent, restart it, and the crwling continues.
How could I solve my issue?
Thanks a lot.
