Yes, logs look fine :-?
Please keep testing instances (custom lists) running for a while, may be some instance will fail later.
We are preparing another testing HML file... if that instance will work fine as well, probably problem within some action :roll:

Just want to keep you guys up to date. I have done two things since yesterday:

1) Rebooted our primary HostMonitor server. It is now only running the normal hostmonitor again (using the recompiled exe). This should be a cleaner test, as I don't think I rebooted the machine itself when I switch exes last time.

2) I have moved all the test HostMonitors to another machine so they don't interfer with the normal HostMonitor. I am running all 8 of the test lists I have received on that machine.

I did both of the above yesterday morning, so it has been about a day so far. I'll let you know what comes of it, and feel free to send any more tests you want me to run my way as I am more than happy continuing to try and find out what is going on.

Update: No problems yet since my last post, on either the normal HM or the tests. All tests continue to run.

So our main Hostmonitor had the bug again. Only this time when trying to bring up a dialog hostmonitor actually pops up a message saying "Cannot create dialog. Looks like the system is out of resources."


One of the test lists finally had a problem also! It is the POP3 test list, and when trying to access a dialog it gives pops up an error with:
"Access violation at address 006270BA in module 'hostmon.exe'. Read address 00000057" followed by a second error "Access violation at address 0042D47C in module 'hostmon.exe'. Read address 3B8BF090" These errors are nearly identical to the errors we have been getting with the standard hostmonitor, I am going to disable all of my POP3 tests in the main hostmonitor and see if that stops it from crashing.

Thank you for information. Yes, please disable POP3 tests.
We are going to check code that performs this test...

Monday morning update: Our main HostMonitor is still running normally. The POP3 testlist HostMonitor encountered the bug again.

Does HostMonitor with disabled POP3 tests still work fine? We have created a lot of POP3 tests to check our servers but cannot reproduce any problem, everything works just fine.
I would say this is antivirus related problem but... you don't have any antivirus. Right?
Probably there is error in our code that appears under some rare circumstances :roll: We don't see it so far :-?
Is it possible to use your servers for testing (if you could create some test accounts for us)? How many different POP3 servers you are monitoring?

Our main hostmonitor with pop3 tests disabled is still running fine. The pop3 testlist experiences the bug all the time, I don't even really restart it anymore.

There is no antivirus running on either our main HM or test HM system.

Our pop3 tests are monitoring 3 servers checking multiple test accounts per server (3 each). Some of the tests use the default timeout value of 60 (9 tests), and some use a timeout value of 1 (4 tests). So we have a total of 13 pop3 tests.

The pop3 test list you provided multiples the same tests mentioned above for a total of 104 tests in the pop3 testlist.

Unfortunately I don't have any servers I could let you personally play around on. I would be more than happy to run the pop3 testlist with a debug exe or more specific testlists or something though.

I thought about maybe trying to construct a POP3 converstation using the TCP test to see if it has the same problem, but I haven't had time to try and figure that out yet.

We modified POP3 related code a little. I don't think that "mistake" could lead to crash... however lets try this update www.ks-soft.net/download/hm684c.zip
If it would not help, we will need to create some special utility for testing....
BTW: Do you use different mail servers in your environment? or may be all servers use the same version of mail software?

All of our pop3 tests are hitting linux machines running Zimbra mail servers. We don't monitor anything else using pop3 tests. I'll put up your custom exe today and let you know if the pop3 testlist still encounters the bug.

Just wanted to give an update. Our main HM still hasn't bugged out since disabling POP3 tests. Additionally, since using the newest exe the POP3 test list is still running fine too.

So, we have fixed the problem? :roll:
Are you going to test HostMonitor 6.84c for a little longer and then replace production exe module and enable POP3 tests?

I can't say that it is fixed, only that it isn't crashing. I'll keep it running for a couple more weeks to be sure.

Right now though we are planning to just stay on 6.80 with POP monitors disabled since this seems stable, and the stability of the system is worth more than monitoring a few POP servers. If there are other features we want in the future we may upgrade then.
