Hi

I had to rebuild my PC, and since then then the LHC runs for 10 sec and then says computation error. the Event Log has no useful info. I've reinstalled VM too. Can you point me to a fix.

One more question, I haven't found a way to reduce the number of CPU cores. In VM its greyed-out and says 6 cores.

Hi

The projuct ran for 3 day then complained that it ran out of disk space.

What is the max. disk space required. Just upped it to 100Mbs from 20 Mbs is this enough ?

Hi

All the LHC apps have high memory usage, and don't seem to release after it has finished a job. Steadily climbs till its almost at the limit of PCs memory of 16Gbs. The preferences are set to 50% in use and 80% not in use, but climps to about 14.9 all the time, making the PC slow.

What am I missing ?

8) Questions and Answers : Windows : High RAM Usage (Message 44187)

Hi

LHC is using very high RAM memory usage. At the start its around 5GB and climbs to almost the Max of 15GB over a number of hours, and stays there slowing the use of other PC applications.

If I shutdown Bionic it will drop back to 5GB, but slowly climb back to 15GBs.

What is causing this issue, as I don't remember in the past it use to do this.

When I did a search on this I didn't find anything.

Is this normal ??

Hi

I changed the network activity from "network activity based on preferences" to "network activity always" and now runs.

I don't understand why I have to do this when the preferences area has no checked boxs to limit it in any way.

Thanks for your assistance anyway.

Hi again

Ok it ran after the VT-X fix and reboot. It ran for 4 hrs one of them, the others started later I guess. Then to make sure all was OK I reinstalled Bionic and Virtual Host.
A day later I note it is saying again "waiting for Network access"

What have I done wrong?

Hi
The last few work items over the last couple of weeks have just sat there waiting for network access. Is there an issue or what needs to change ?
