IMAPS.exe blocking on access to activity lockfile

Postby airbear » Sun Oct 29, 2017 4:53 pm

Hi,
Since recently upgrading from ME Enterprise 9.62 to 9.78, we are now intermittently seeing MEIMAPS.EXE blocking and logging the following error to the Windows event log:

General: (MailEnable IMAP Service (D:\MAILEN~1\Bin64\MEIMAPS.exe) error: 32) ME-EXXXX: [Thread:7268] Error (Class S): BlockFileLock Activity notification handler (WaitForAccessToFile) failed to obtain a lock on the blockfile (D:\MailEnable\POSTOFFICES\postoffice\MAILROOT\user1\_activity.blk).

We didn't ever see this previously and I was wondering if this is a bug or, if there's anything we might do to prevent this from happening?

Thanks,
Aaron

Hi,

It just means that another service is currently accessing the _activity.blk file and has locked it so that no other service can write to the file at the time. In this case we write this out in the Windows event log. As to what other service had a lock on the file I don't know. Could be web mail, POP, ActiveSync etc.

Thanks Ian,
Do you have any idea what changed between 9.62 and 9.78 which would cause this blocking to become an issue for us?

Regards,
Aaron

Hi,
We are seeing recurrent IMAP service instability (unresponsive but still running or sometimes stopping altogether), since we upgraded to 9.78. I'm not sure if waiting for lockfiles is the problem but, the only logs I see are the timeout waiting for lockfile.

1. Are you aware of and working on this issue of IMAP service instability?
2. Is there a procedure for rolling back to an earlier version?

Thanks,
Aaron

Hi,

1. Are you aware of and working on this issue of IMAP service instability?


There are no current IMAP service instability problems. In order for us to diagnose the problems in more detail it would be best to lodge a support ticket and provide RDP login details or a Teamviewer session to the server so we can troubleshoot in more detail and review the relevant log files.

2. Is there a procedure for rolling back to an earlier version?


You can review the following article which explains how to downgrade MailEnable which can be applied to downgrading to a previous version: http://www.mailenable.com/kb/content/article.asp?ID=me020375. Although as mentioned the best way forward would to diagnose your problems with 9.78.
