B Troubleshooting
Authentication
On a Linux or ESX system, you might receive the following error when running the mxagentconfig
command or through Configure or Repair Agents:
Configuration failed to complete due to the following exception: Could
not access the file or directory sshd_config.orig on the target system
esxhost1. Remote system reported following error message: Permission
denied. Check whether the directory or file exists or whether the user
has the operating system permission to access it.
Solution:You must manually change the permissions in the file to 644.
Browser
If you are using a Firefox browser, you should avoid remaining on the Task Results page for an
extended period of time. If you notice the browser becoming sluggish while viewing the Task
Results page, you should sign out of Systems Insight Manager to allow the browser to release
memory. You can then sign back in.

My Browser is displaying an error message Communication with the Systems Insight
Manager server has been lost
.
Solution: The Systems Insight Manager portal relies on the CMS to respond quickly to all requests.
•
If the CMS is slow to respond to one request, browser performance can fall significantly during
that time.
•
If the CMS is slow to respond to two requests, the browser appears to lock up completely
during subsequent interaction; the browser does not send additional requests until there are
fewer than two outstanding requests.
•
If four sequential ping-like requests takes more than 30 seconds each to complete, due either
to request queuing or slow CMS response, the browser displays the message, Communication
with the Systems Insight Manager server has been lost
, even though the
CMS might still be responsive to other browser sessions.
By default, web browsers are limited to two simultaneous connections to a single web server. If
two requests are outstanding, any additional requests wait until one of the current connections
completes. This is by design and is in agreement with the HTTP 1.1 specification. The Systems
Insight Manager UI generates many requests, many of them simultaneously. The Systems Insight
Manager portal relies on the CMS to respond quickly to all requests. On a LAN, the browser
receives a CMS response to most requests within 10 to 100 milliseconds, which is nearly
instantaneous. Requests that involve database queries or secondary network communication might
take a few seconds to respond. The following situations might result in particularly slow response
times:
•
Viewing large collections of systems or events.
•
Specific or custom database queries taking an unexpectedly long time.
•
Many users simultaneously accessing a shared resource, such as the database.
•
Pages (for example, System Properties) that retrieve data using WBEM or SNMP and display
the results, especially when the requests are destined to time out.
Solution: The maximum number of server connections can be increased in both Internet Explorer
and Firefox. The default number of connections is two. Though you can increase this number into
the hundreds, it's recommended not to exceed ten. For more information, see:
