Dear Bioconductor, I'm trying to use Rsubread in an Ubuntu virtual machine:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"
NAME="Ubuntu"
VERSION="18.04.2 LTS (Bionic Beaver)"

PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=bionic
UBUNTU_CODENAME=bionic

I tried to increase virtual's machine RAM :50 Gb ~ 80Gb but I still have the same issue. When I run the align command

 alignmentmRNA <- align(index = path,
      readfile1 = data,
      type = "rna",
      input_format = "FASTQ",
      output_format="BAM",
      nthreads = 10,
      sortReadsByCoordinates = TRUE,
      useAnnotation = TRUE,
      annot.ext = path_gtf,
      isGTF = TRUE)

I get :

What is the configuration of the host computer running the virtual machine? Say, is it a Windows computer or a Linux computer, and what virtual machine software was used? How much physical memory was available on the host computer?

Could you share the input fastq file and the reference genome used in mapping, so we can find out the cause of the error? Also could you provide the command for index building?

Thanks for sharing the data.

I used your fastq file, and used the same reference genome fasta file and the same annotation gtf file (the latter two files were downloaded from GENCODE). I also used your command lines. Rsubread_1.34.6 did index building and read mapping smoothly; around 95.5% reads were mapped to the reference genome. Now I'm curious if the error is specific to this fastq file or any fastq files? How about running Rsubread on the host computer (CentOS 7) directly?

BTW, I ran Rsubread on a CentOS 6.4 computer with 512GB memory, and not in a virtual machine.

If it is possible, can you try running R in gdb :

$ R -d gdb

then

(gdb) run

This will start an R session, then you can run the align function as usual. When something goes wrong, it will fall back in gdb, then you can use

(gdb) where

to see where exactly the error happens.

Sorry for the late response -- I now have an environment to reproduce the error.

I found that Ubuntu 16.04 doesn't have this problem but Ubuntu 18.04 has it. It looks like R didn't actually release the memory allocated in the index-building step, although the index builder itself has called the memory-releasing function to do so. I'm digging dipper to see what caused the problem.

I found that the very many "malloc" calls in the index builder make the heap of the R session a bit messy -- nearly every memory page contains allocated and not-allocated blocks. On a computer that has a huge amount of memory, there are still enough non-contaminated memory pages, but on a computer that has a memory size not too much than the index size, this will exhaust all allocatable memory pages, hence preventing the malloc() function called by the aligner to allocate a 16GB continuous memory chunk for the index.

This issue has been solved by pooling the very many tiny memory blocks in the index builder into very few continuous memory chunks. This can guarantee that virtually all memory pages are fully freed at once after the index is built, hence allowing the allocation of the huge continuous memory chunk to the aligner. This change will be merged into the released version of Rsubread package after the release of Bioconductor 3.10.
