Is my Host messing with me ? Sites keep going down they keep trying to upsale me to the next level of VPS..

I see it is "oomguarpages " that is always going in the red zone even with "low numbers" ..all other numbers look good ..appreciate some help sorting out what is going on

Possibly. oomguarpages is your RAM guarantee - the real question is: why are you exceeding your memory allocation? How much RAM should you be getting?

Unfortunately I'm not an expert with OpenVZ implementations (I assume this is what you have) so I don't have a real response - perhaps others using a VPS of this type could comment?

Thanks Encyclo..

I have 1 Gig of ram and at the moment it is showing

Memory Parameters
Parameter Current UseSoft LimitHard Limit Units Description
slmmemory limit 248.51 512 1,024MBSLM memory limit

so 248 used.. just cruizing down the highway.. no issues with that or disc space (60% used)

etc..

But even with those numbers oomguarpages is in the Red Zone even though my Soft Limit is below the 65 they have it set at..

Current Softlimit
59,547 65,536 maximum 4KB pagesOut-of-memory guarantee

I am looking at it through Parallels VPs manager

Also note .. I noticed this Text when Highlighting the "red zone "image"

-Red Zone: Critical situation. The parameter exceeded its soft limit or came very close to the hard limit. Your next resource allocations request may be refused.

And Yet all of my resources are well within limits..except this oomguarpages

Host has Softlimit set at 65,536 and "maximum" for Hardlimit..

I suspect I was given low 'max" ?

While I have the "Red Zone" for oomguarpages ....I am only using 24% of total mem.. So I don't get it

Memory Usage
ResourceUsedFreeTotal
Memory
244.2 MB23.85%
779.8 MB1 GB

There very well may be an valid explanation but I haven't gotten one form them ..just that I am using more resources than allocated

BTw....as you all probably know anyway but

" Your next resource allocations request may be refused"

.thats when all the sites start going down.... I can reboot and they all go back up for 3-4 days then they go down again

UPDATE: I was on the right track .(hey it actually happens once in awhile;)

They upped the Softlimit on oomguarpages to reflect the Plan I actually purchased.

The Plan I purchased was originally 256MB Ram ..they were running a special and doubling Ram, Bandwidth etc..on all the Plans

when they set the VPS they didn't double all the settings... So I was Red Zonning and sites were going down.

Savings $35 x 12= $420 (If I had simply moved to the next size Plan)
