Restart TomEE frequently because URL is not responding
Good morning, i need your help please
In a Production system an application comprises TomEE and the core application, and it is distributed among 4 nodes or servers
Many many times the URL for node1 its not responding, sometimes there is a delay of 2 mitutes to load,sometimes i get a 404 error, so the temporal solution is to restart tomEE almost daily, but this is not a good practice because this URl receives thousands https requests from internet.
behind those 4th nodes it is a load balancer, so these questions arise:
1 when and why should i restart tomEE? how frequently?
2 in Unix/Linux itself is a way to see for each node the number of request being received from the load balancer? so i can know if LB is sending the request in a balanced way to each node?
I am new to Unix and i have no idea about web servers applications, if u have any url to get documented
I appreciate your help in advanced

cmcp(1m) cmcp(1m)
NAME
cmcp - Copy files between Serviceguard nodes
SYNOPSIS
cmcp [-rv] [src_node:]src_file [...] [dest_node:]dest_file
DESCRIPTION
cmcp copies files and/or directories between Serviceguard nodes.
cmcp is limited in several ways. cmcp is best suited for situations where other remote copy facilities are not available. For a more full
featured tool for copying files between Serviceguard nodes, see ccp(1m) provided by Distributed Systems Administration Utilities.
To use this command, the local user must have the root access role on each of the involved nodes. For more information on Serviceguard
access control policies, see the manual, Managing Serviceguard.
Paths may be relative to the current working directory or specified absolutely. The current working directory on a remote node is assumed
to be the same as the local node's directory. Copies between two remote hosts are permitted.
If a file or directory already exists on the destination node, the destination node's copy will be overwritten with no prompting.
The cmcp command is not suited for large files or large numbers of files and may result in a heavy load on the command and Serviceguard
daemons. Other tools such as ccp should be considered for these purposes.
Options And Arguments
-r Recursively copy entire directories.
-v Verbose output will be displayed.
src_node
Serviceguard node to retrieve the file from. Defaults to the local node.
src_file
Path to source file on src_node.
dest_node
Serviceguard node to copy file to. Defaults to the local node.
dest_file
Path to copy src_file to on the dest_node.
RETURN VALUE
cmcp returns the following values:
0 Successful completion.
1 Command failed.
EXAMPLES
Copy the local file /etc/hosts to remote node node1
cmcp /etc/hosts node1:/etc/hosts
Copy the remote file /etc/passwd on node1 locally
cmcp node1:/etc/passwd /tmp/passwd.poe
Copy a local script directory to a remote node
cmcp -r /etc/cmcluster/scripts node1:/etc/cmcluster
