R Increase Memory
a memory problem when searching a large amount of data. I was searching data hour by hour. It works fine at first, but after a few times, the error appears: "Error in readBin(content, character()) : 'Calloc' could not allocate memory (47456329 of 1 bytes)" I tried to restart the R session which memory limit r didn't help. When I restart the computer, it came back to normal and appeared again after the same searching process. When this problem happens, the Elasticsearch server was running well. Here is the code I use to do the work: body <- list(query=list(range=list(peb_time=list(gte="20150620210000000", lte="20150620220000000")))) Search(index="pebble", type="mov", body=body, size=200000, sort="peb_time") Do you have any idea why this happened? Did I do make some mistake? Thank you very much! Zheng sckott self-assigned this Jun 24, 2015 rOpenSci member sckott commented Jun 24, 2015 hi @zhengxiaochen - Thanks for your report. I tried the same settings with some local data I have, but I can't replicate the problem. How much memory is on your machine? When you have that problem, can you check to see if your computer's memory is low? One solution may be to simply split up the query into smaller chunks, e.g., 50,000 per query. Another option is using scrolling - see egs here https://github.com/ropensci/elastic/blob/master/man-roxygen/search_egs.r#L323-L358 Elast

But, when I am fitting a model this shows some kind of problem. (My sample size is n=4500) library(timereg) fit <- Gprop.odds(Surv(time,status==1)~prop(age)+prop(sex)+prop(fedu)+ prop(wi) ,dat,max.time=7,n.sim=400) Error in Gprop.odds(Surv(time, B5 == 1) ~ prop(mageB) + prop(B4) + prop(fedu) + : 'Calloc' could not allocate memory (13583 of 8 bytes) How can I solve this problem? Thanks for http://stackoverflow.com/questions/31330166/how-can-i-solve-memory-allocation-error-in-r your time. r out-of-memory share|improve this question edited Jul 10 '15 at 1:11 user227710 2,504725 asked Jul 9 '15 at 23:42 Rudro88 4519 What is the value of memory.limit() ? How does that compare to you system RAM? You can expand memory via memory.size( size ) , size specified in MB if you want more RAM available to R. –Josh W. Jul 9 '15 at 23:45 Values are memory.size() = 48.05 and memory.limit() 3000. My RAM is 2 GB. How can I solve this problem? –Rudro88 Jul 10 '15 at 0:02 well your memory.limit() > RAM so that's not the issue. Try using a random sample of your data. Otherwise we don't know enough to help. We don't know what else is using your RAM. –Josh W. Jul 10 '15 at 0:10 The amount of memory requested that caused the error is tiny. Some other process, possibly not related to R is consuming free space. Restart your computer with minimal number of applications running concurrently and try again with as few objects in your workspace as possible. –42- Jul 10 '15 at 0:24 Its working. Thanks a lot for your suggestion. –Rudro88 Jul 11 '1
Next message: [R-sig-DB] RODBC Error when fetching tables: 'Calloc' could not allocate memory Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] memo fields are an issue for MS ODBC and https://stat.ethz.ch/pipermail/r-sig-db/2015q3/001525.html MS Access or SQL Server, especially with sqlSave() creating or appending to tables. ODBC reports https://groups.google.com/d/topic/ggplot2/enavD18MmkY them as 1G 2-byte characters per value, VARCHAR with length of 1070M or so. As far as I know, this is an all-MS issue, between their ODBC and their databases, and on most if not all platforms. sqlColumns(mdb,table) is another way to accomplish what you do with x <- sqlQuery(con, paste("exec sp_columns", tables[i], sep=" ") ) x memory allocation <- sqlColumns(con,tables[i]) I may be brain-dead, but I don't think you need the which() in your subsetting: drop.cols <- as.character( x[which(x$LENGTH > 8000),]$COLUMN_NAME ) drop.cols <- as.character( x$COLUMN_NAME[x$LENGTH > 8000] ) Tom 2 On Wed, Jul 22, 2015 at 10:41 PM, Brad P
