after upgrade to 8.84, VbScript tests failing intermittently

[fspiper]

We just upgraded Host Monitor from 6.82 to 8.84 and we're experiencing a new problem which we did not see in the older version. The test, a VbScript, fails to run and does not appear to ever get called. The Host Monitor log shows the result
"Unknown"
immediately followed by
"Error: Cannot create temp file. The file exists."

The Host Monitor PC is running Windows XP SP 3; it has 1Gb RAM and about 35Gb free disk space.

We run a few dozen copies of the same VbScript test against remote servers every ten minutes around the clock. This means that occasionally the test is run on more than one server simultaneously; this was not a problem with the old version of Host Monitor.

The problem is occurring six or eight times a day. The problem is not associated with specific servers; it jumps around randomly.

All tests have the same parameters except for Params, Test name, Comment, and Alert profile.

When the problem occurs, the VbScript does not appear to ever get called. (The VbScript has its own log, and nothing is written to that log.)

The test description is as follows. (I obscured our customer's info by replacing it with "xxxcustomerxxinfoxxx".)

After checking the forum for similar occurrences, I confirmed that the userID that Host Monitor runs under has access to C:\temp and C:\Windows\temp, and also confirmed that the shortcut used to start Host Monitor has the correct directory for "Start in:".

If there is any solution, or anything else I can check, please let me know ASAP.

Thanks for your help.

Never seen such error...
Theoretically it may appear when HostMonitor cannot create any unique file name within specified pattern (e.g. HostMonitor runs for a while, creates temp files for scripts but unable to remove these files).
Could you check Temp folder? Is there a lot of files with name started with "tmp-"?

Note: If HostMonitor is started under some user account, you should check Temp folder specified for this user account (probably something like c:\Documents and Settings\UserName\Local Settings\Temp)
If HostMonitor started as service under local system account, Temp folder probably C:\Windows\TEMP

Thanks very much for the reply.

HostMonitor should removes temp files after Shell Script test execution. Why these files were not removed? Hard to say
