7.6 kernel.exe consumes more memory than 7.4

[Former Member]

Hello!

After installing version 7.6 on Windos XP I've noticed that kernel.exe process takes 0.5G more of VM size than in version 7.4 with same configuration (950M instead of 450M CASHE_SIZE is 32786).

Why is that?

Thanks,

Hello Anya,

you can check the parameter history if there are some other parameters which consume more memory with 7.6 than only the Cache-Size.

You can check the system table allokatorstatistics as well to get more detailed information which component is responsible for the memory allocation.

Hope this will help you.

Hello!

I set CACHE_SIZE to minimum, but the process still consumes about 600M of virtual memory after restart and with 0% data use and do user activity. I attach select * from allocatorstatistic with most significant entries. All the db parameters are default and I did not find anything after comparing with parameters of old version. Is it minimal requirement of kernel.exe?

Thanks,

Anya

Well, I found "leaked" memory.

MAXDATADEVSPACES=250

was replaced by MAXDEVSPACES=250

which apparently consumes a large amount of memory. I lowered it to default 10 and memory usage dropped
