I currently use memcron for my PS server – ps4815 .

How can I also use memcron for my PS SQL – psmysql12794?

How to setup for the PS SQL and PS server at same time in Crton job?

Hi Robert, thanks for confirming the upper swap memory limit of 900MB, that’s what I would have guessed.

I’ve tried to make the calculation as modular as possible starting from version 0.4. I believe there won’t be much benefit to make it any simpler, you sure you aren’t looking at older code? Anyway, thanks for the suggestion.

I’ve released a new version of memCron to address the recent swap memory change. Please give it a try and let me know if there’s any issue.

I would also be willing to beta test this for you Yaosan.

DreamHost hasn’t announced anything about the change to swap memory yet.

I noticed in the memcron code that there are several places where the swap size is calculated. It might be a good idea to move all of that to one function.

Yaosan,
Thanks for the work you put into this! Could we get a public copy of the changes you made and are testing with? I’ll gladly test it and report back. Thanks!

I can confirm this changes. They seem to add twice the physical memory as swap, with a 900 MB upper limit for swap.

Yes I fixed memCron to account for the increase of swap memory and I’m doing some testing with it. So far there hasn’t been a spike big enough to trigger the memory change so I’m not exactly sure if it is working properly.

I’ll probably just go ahead and release the patch and get feedback from users who use a lot of memory on their servers.

Yaosan, The demo seems to have leveled off at 150Mb. Did you fix memCron or did you disable memCron and force the memory to stay at 150Mb via the DH panel?
