[jboss-jira] [JBoss JIRA] (WFLY-2862) Liferay too many open files during deployment

[Jakob Munih (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-2862?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jakob Munih updated WFLY-2862:
------------------------------

    Attachment: dump-9406-514


I was forced to set the ulimit  up to more than 10k to be able to deploy LR. The file dump-9406-514 captured the 514 iteration of calling lsof after server start up that logs 9406 open files. As soon as LR deploys the number of openfiles  fails down to 1.2k. Issue not present in AS7, where the number of open files can rest on the linux default (1024). 
{code}
#!/bin/sh
PID=`ps -ef | awk '/[j]boss/{print $2}'`
echo $PID
N=1
while true;
	do
	content=`lsof -p $PID`; 
	lines=`echo "$content" | wc -l`
	file="lsof_logs/dump-$lines-$N"
	echo "$content" > $file;
	echo $file
	N=$((N+1))
done

> Liferay 6.2 deploys as an exploded war. Normally after deployment it builds a theme (css/js boundles). Even if only Liferay is deployed a Too many open files exception is thrown. When /proc/sys/fs/file-max is 6815744. While trying to configure it or deploy other portlets (exploded wars too) the too many open files exception is encountered even at the deployment time (server start up).
