centos 6.7 and we can not update it (vendor specific)
Please tell me this isn’t public facing with a portal or something. I don’t think 6.7 even has EUS anymore since it’s past 24 months from the release.
I honestly have not had an issue like this so I can’t really give any insight.
What software is this?

, the linux OS is not the latest it is centos 6.7 and we can not update it (vendor specific)
OMG - say it isn't so - you mean platforms other than Windows have this issue? I just can't believe it /sarcasm off

Sadly we have software that required something similar to be “supported”. We do internal QA of all of our software and found that being on 7.4 vs 7.3 made no difference so we updated. It actually works better on 7.4 anyway.

theoretically it should work on 6.8 but I cant make that decision.
No its not internet facing. -
It is software from software company with 5000+ employees
and are in 14 countries.It really not the vendor 100% fault, our EMR manager is semi-nice looking female + expat = that what matters where I work.

I think he means that people are going to listen to her even if she makes bad decisions.

I only ask because I knew of one that ran on CentOS but never knew what version. It's probably not the one I'm thinking of.

In reading that again - is he saying that because he's not a hot lookin' expat, that his ideas are worthless? if not, then again - I have no clue what's he's on about.

The issue is the app, not the OS.

He's saying he works in the real world where a hot sales girl has more sway than the IT team.

Yes Scott I know... but this is generally something much more associated with Windows than other platforms. Of course this in no way implies that it never happens on other platforms...
oh and you did see the /sarcasm off part, right?

I never use cache dropping. Any reason you don't just reboot? I mean both are pretty awful, but if this system is critical it'd be rebooting regularly anyway. Might as well do the two together.

I see the sarcasm bit but don't understand it nonetheless.

@emad-r Your flushing the kernel level block storage cache, of course there are downsides. I've not run into an issue where flushing the caches actually fixed a memory leak issue, either. All you're doing is delaying the inevitable crash.

Did I understand correctly that it's a Java application? If so, how are you launching/running it? What CLI command you using?

While impacting IO.
