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 10–100
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:
