Failure to load data

Hi,

I'm just encountering a very weird error.  I was just trying to create a new peer certificate when after clicking on create, the webconsole spins for a bit and then it displays "Failure to load data" and then it promptly logs me out.   Now when I try to log back in, it shows a small message above the login part " Login failed: Connection has failed with state 'Not connected'.  After a bit, it'll allow me to log in; but when I do, it then shows an error "Failed to load tags" and then it boots me out.  Now it won't let me log in.

I go onto the server's event viewer and noticed this error: The ESET Security Management Center Server service terminated unexpectedly.  It has done this 3 times.

So I go and restart the ESMC server and try to log in.  Unfortunately, it immediately gives me a "Failed to load all tags." error and then after clicking the OK, it gives me a 2nd error:  Failed to load data report resolving failed: null.   I click on ok and it boots me out again.  So I restart the ESMC server again...

I'm feeling it might have something to do with me creating an ad hoc tag during the certificate creation stage.   Not entirely sure; but I feel the database has been horked.

Right now, I'm going into the database (which thankfully is MySQL based) and figure out which table his horked and hopefully fix it; otherwise, I'll need to do a complete reinstall (unless someone else has a good idea).

Managed to unhork the database by the following (luckily I had only one tag):

  1. go into mysql
  2. select the era database
  3. delete from tbl_tags_zig;

Restarted the ESMC server service, and now I can log in.

Steps to reproduce this issue:

  1. Create new peer certificate
  2. Enter the necessary information as required, particularly for the first screen where it allows you to specify a tag, you click on "select tag" and then enter a value that isn't in your tag list.
  3. finish up the certificate signing and click Finish
  4. It will then state that the Certificate has been created; but would then follow up with a Failed to load data and then it'll log you off and the ESMC service will crash.

Addendum:

I looked at the database tables that I think are related to tags (namely, tbl_tags_*) and found that while the test tag I created got entered into tbl_tags_zig,  none of the other 'related' tables were ever modified in that they were all empty.   So I what I think happens is if you create an ad hoc tag, it adds it to the tbl_tags_zig,  with the blockdata; but not actually update/add anything else to the other tables (as I speculate that the tbl_tags_data should also have something added to it as referenced to it).

Could you confirm that the system where ESMC Server is running on is powered by an older CPU without support for SSE4 instructions?

Hello, I have the same problem. My ESMC runs on older CPU. Is there any solution?
