I am experiencing a memory allocation error with R 2.6.2 which was not present in previous versions of R (2.4 and 2.2). I have several Linux machines with various Redhat OS versions loaded on them, ranging from 4.2 through 4.5. Each machine has 6 GB of RAM and 2 to 4 GB of virtual memory. The processes I am running include calculations on large matrices (1,015 x 2,029). While the programs are large users of memory, they were stable (i.e. no memory crashes with the earlier versions of R) on all machines. However, running the same programs using R 2.6.2, I consistently get the error message "Cannot allocate vector of size 15.7kb". I am calling the programs with the --max-vsize=3G command...no difference. Using a garbage collection command, I can see that the programs never use more heap than 2.5 GB. And, as stated before, this was not an issue when the same machines were loaded with R 2.4 or 2.2. I have verified that the OS settings are exactly the same as before (unlimited allocation of memory to programs). Also, when I re-install R 2.4, the programs run correctly. I have not been able to test R 2.5 or R 2.6.0, since I cannot find binary packages of these versions, and I have yet to compile the source code. Any thoughts? ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
