We have two GPFS clusters. One is fairly old and running 4.2.1-2 and non CCR and the nodes run fine using up about 1.5G of memory and is consistent (GPFS pagepool is set to 1G, so that looks about right.)
The other one is "newer" running 4.2.1-3 with CCR and the nodes keep increasing in there memory usage, starting at about 1.1G and are find for a few days however after a while they grow to 4.2G which when the node need to run real work, means the work can't be done. I'm losing track of what maybe different other than CCR, and I'm trying to find some more ideas of where to look. I'm checked all the standard things like pagepool and maxFilesToCache (set to the default of 4000), workerThreads is set to 128 on the new gpfs cluster (against default 48 on the old) I'm not sure what else to look at on this one hence why I'm asking the community.
