Http task and memory usage

HCL Domino Domino Forum

I’m upgraded Domino 5.06 to 6.03. Several times a day some of web application users’ browsers freeze. When I look at task manager, I see that HTTP task on the server is using about 250 MB of memory. The OS is NT4 Sp6a. CPU is PII. Digital server.Is it a way to limit HTTP memory usage?

How can I determine what the reason of this problem exactly?

Hakan,

this is the way to restrict Domino from using more Memory then available !!

ConstrainedSHMSizeMB setting in notes.ini

this sets the maximum MB using of virtual memory

for example ConstrainedSHMSizeMB=512

more info is available in the ini reference :

Good luck…

Subject: Same Problem & ConstrainedSHMSizeMB doesn’t help

We have the same problem – Win 2000 SP4, R6.03. Server box has plenty of memory – 2G. Site is accessible via https only.The ConstrainedSHMSizeMB set to 500 and it doesn’t fully help. The speed of eating memory by http is reduced but not eliminated. If ConstrainedSHMSizeMB set to something higher than 500 (I’ve tried 1024, 768 & 512 the server crashes more quickly even the box has 2G of RAM !!! When ConstrainedSHMSizeMB set to 500 server doesn’t crash but http task does.

We have to restart http task via server scheduled programs two times a day to release the memory and prevent crashes.

I’ve been discussing this issue with others, they say that the problem does not exist on SP3 boxes, but after SP4 install the problem appears… My problems appeared after I installed SP4…

Subject: SOLUTION: https memory leak

IBM has finally come up with the hot fix – 653HF298_W32. It was a memory leak during HTTPS authentication (X.509 certificates in our case). It fixed the issue.

Hi Raj,

I don’t think there is a URL. You need to contact IBM support to get it. It may be already included in 6.5.4 but I didn’t check.

We have the same problem. Same upgrade: to 6.03. HTTP task uses approximately whole memory, then server crashes…
