The app generates many files that are never closed in ubuntu 16.04.

Hi, I have been looking for a solution like yours for some time now. currently on my tests I am having this problem that the APP does not close some files it opens. I have had the application running since yesterday. check this out:

root@zaabix:~# ps aux |grep mast
root     21172  0.0  0.0  14224  1084 pts/0    S+   15:38   0:00 grep --color=auto mast
root     30636  0.4  9.3 448620 376408 pts/1   S+   Jan29   5:29 perl /usr/bin/masterha_manager --conf=/etc/app1.cnf
root@zaabix:~#

Then this is how many files the software is using right now:

root@zaabix:~# lsof -p 30636 |wc -l
27279
root@zaabix:~#

lsof also show what those files are:

# lsof -p 30636 | head -n 200

My config is as follows:

# cat /etc/app1.cnf
[server default]
# mysql user and password
user=root
password=6U6hRVrFsnnA5ZgD
ssh_user=root
# working directory on the manager
manager_workdir=/var/log/masterha/app1
# working directory on MySQL servers
remote_workdir=/var/log/masterha/app1

manager_log=/var/log/masterha/app1/replication_check.log

[server1]
hostname=host1
master_binlog_dir=/var/lib/mysql/data

[server2]
hostname=host2
master_binlog_dir=/var/lib/mysql/data

Why do you think the Application would do suck a thing? Regards and thanks Abel
