Hey There.
I am running Linux and having a problem with Matching Cancer Markers (MCM).

Is this the same problem - or should I start another post?
I have 11GB of memory, and 8 processors, yet I see
- 12 different (by process ID ) boincmgr tasks running - each using 98 GB of VM
- 10 processes of WebKit process - each using 97 GB of VM
- 11 processes of WebKit process - each using 81.9 GB of VM
I was running
- 1 WU of Einstien with 1.0 dedicated CPU
- 4 WU of MCM
- 3 WU of MIP
- I have
- Let all WU complete; Reset and removed projetcs; Removed and reinstalled BOINC - and cold shutdown and restarts several times.

of User/System times - about 25 % of each WU process is in system time (by htop and gkrellm)

HOWEVER, vmstat and the system monitor shows less than 25% of my memory used.

My BOINC Computing Preferences include:
- Memory - CPU in use: 80%
- Memory - CPU Not in use: 80%
- Page/swap file : 75%

System monitor shows NO swap file in use. (0 of 48.83 GiB)

I am stumped.
Also, Boinc Event Log shows no errors. Here is what it says:

THanks in ADVANCE!!

PS
Extensive memory tests show no error.
Read/Write of every block in that partition holding /var shows No errors.
I don't always get this problem. I don't always run MCM.
I am aborting and letting all MCM tasks complete and will reboot and seen if the porblem continues.
(( Stay safe out there!! ))

PPS
The use of sytem time goes away whem no MCM WU running.
However 32 (!) BOINC-related tasks are *still* using 98, 97, or 81GB of memory.

Hello Mike,
That is what I am doing. Einstein WU runs on GPU - but I have 1.0 CPU assigned to support the GPU - leaving 7 of my kernels to crunch WCG.

Do you see any weirdness with MCM??

I experienced this issue on Windows based systems in the past. After an undefined timespan the WU (Zika or MIP) resets itself, restarts from the last checkpoint and finishes successfully. If you want to speed up the process close BOINC with the option to stop all running tasks. Open task manager and search if there is a project related task still listed (in my case the affected task won’t stop gracefully) and aboard it. Restart BOINC and start processing again. I never experienced that the same task run in this issue twice.

And here is a new version of that issue:
