Lansweeper service crashing

[Geno]

Has anyone else had this error before?
>

Source: .NET Runtime 2.0 Error
ID: 5000
EventType clr20r3, P1 lansweeperservice.exe, P2 3.5.3366.20178, P3 49c36ca5, P4 system.data, P5 2.0.0.0, P6 471ebf27, P7 246d, P8 2c, P9 system.data.sqlclient.sql, P10 NIL.

I realize this is due to the .Net framework I have because it doesn't happen on a different machine. But how can I solve this?

Edit: I take that back. It did happen on my other servers aswell.

We found indeed a problem in the checklicense module.
It will be fixed in 3.5.1

I'm sorry I forgot:
23:32:34

Exactly at the same time. Which is why I asked about the error handling.

[Geno]

Now that you mention it, I did put it down for maintenance.
But why would that make the service crash?
Is there no error handling when the sql server can not be reached?

Yes there is, otherwise it shouldn't write into your errorlog file.

At what time did this problem occurred in your eventlog?

[Hemoco]

Most likely your sqlserver stopped working at that time?
