After upgrading from 7.0.3 to 8.5.1 we are facing recurrent following problem:
Web Users apparently face very slow response from server for quite some time and it happens twice a day.
For this we have to restart HTTP Task.
If Http task doesn’t restart, after a while HTTP stop responding. Users are not able to browse web mail login page. To coupe up this situation we have to restart Domino Server.
our 75% users using web mail. any suggestions?
Subject: We had a similar issue
We had the same symptoms occurring at one of our clients and it ended up not really being related to the HTTP task at all. We saw HTTP user experience slowing down and after a bit we had to restart HTTP to get back to a decent response time. The underlying issue though, had to do with the Indexer task and all the things we were trying to make it do. As time went by, the Indexer task became more heavily burdened until requests by the users (almost all were HTTP users) were severely delayed or timed out since the Indexer task couldn’t serve up the requested information to the HTTP task in a timely manner.
Now, for us, we saw this at R8.5 and going to R8.5.1 fixed the issue (there was a change in the way soft deletions were managed that was reverted in R8.5.1 that fixed our problem). However, even though this may seem unrelated, perhaps what will be of help to you is to look at other tasks that provide info to the HTTP task or to whatever your users are doing.
For us to get to the solution for our problem was a multi-week, multi-IBM Tech Support person investigation; hopefully you will be able to find something easier to fix on your box.
But, the Index task might not be a bad place to look at.
